What's next
A roadmap to the future developments of Brainstorm.
Contents
Recordings
RAW file viewer:
- Bottom bar: display extend events as segments instead of dots (to see their extension)
- Downsample before filtering? (attention to the filter design)
- Add parameter to make the visual downsampling more or less aggressive
- Pre-load next page of recordings
- Keep the filter specifications in memory instead of recomputing for every page
- Add field "comment" to markers: For clinicians to add notes (Marcel)
- Events: Change the category of a selected event easily, instead of deleting/marking new
Events: Advanced process for recombining.
Example: http://www.erpinfo.org/erplab/erplab-documentation/manual/Binlister.html
- EEG: Laplacian montage (see doc sent by Jeremy)
- Bad trials: When changing the status of bad to good: remove the bad segments as well, otherwise it is not processed by processes like the PSD.
- Review clinical recordings: Reduce the dimensionality of the data with a simple inverse problem, similar to what we do for the magnetic extrapolation ("Regional sources" in BESA, cf S Rampp)
- MEG/EEG registration: Apply the same transformation to multiple runs
- 2DLayout:
- Does not work when DC offset is not removed
- Add a proper amplitude scale that gets updated when shift+scroll, to compare figures
- Create heat maps: Maybe with matlab function heatmap?
Interface
Add a warning when computing a forward model with > 100000 sources (check selection)
- Multiple screens: Add option to set on which display the main bst window should be
File filters: Add boolean logic: https://github.com/brainstorm-tools/brainstorm3/issues/68
- Snapshot: Save as image / all figures (similar to Movie/all figure)
Generalize the use of the units (field .DisplayUnits): Rewrite processes to save the units correctly
- Colormaps:
- Allow brightness/contrast manipulations on the custom colormaps
- Create a colormap similar to MNE, where extrema are bright
- Global colormap max: Should get the maximum across all the open files
Set parula (or others) as the default, not jet: https://bids.github.io/colormap/
https://jakevdp.github.io/blog/2014/10/16/how-bad-is-your-colormap/
- Open new figures as tab (docked in the Figures window)
- Copy figures to clipboard (with the screencapture function)
- Display warning before opening files that are too big
- Smooth display from figure_image (ERPimage, raster plot...)
Contact sheets & movies: use average of time windows instead of single instants, for each picture.
- Contact sheets: Allow explicit list of times in input (+ display as in MNE-Python with TS)
- Display CTF coils: Show discs instead of squares
- Use boundary() instead of conhull() in all the display functions (ie. 2DDisc)
Connectivity
- Thresholding and stat tests the connectivity matrices
- Connectivity on unconstrained sources: "Default signal extraction for volume grids should be the time series of the first principal component of the triplet signals after each has been zero-meaned" (SB)
- Display of connectivity graphs:
- Display as straight lines
- Recode 2D graphs
- 3D display with anatomical constrains
- Display using real position of EEG electrodes
- Use new band-pass filters in bst_connectivity ('bst-hfilter' instead of 'bst-fft-fir')
Review by Jan-Mathijs: http://journal.frontiersin.org/article/10.3389/fnsys.2015.00175/full
- Connectivity based on band limited power (Sylvain):
- Compute Hilbert/Bandpass + correlation of the envelopes
- Bandpass envelopes before computing correlations?
- Compute Hilbert(sensors) and then project to source space?

- Fixed scales for intensity sliders
- Text bigger
- Too much data in appdata
- Fixed scales for intensity sliders
- Add "=" shortcut for having graphs with similar configurations

- Time-resolved correlation/coherence: Display as time bands
- Other metrics:
- Coherence by bands: bst_coherence_band_welch.m
- Granger by bands: bst_granger_band.m
- Inter-trial coherence
Tutorial coherence [1xN] : Reproduce FieldTrip results?
Connect NxN: Display as time series > Display warning before trying to open too many signals
Processes
- Use CUDA for speeding up some operations (filtering, wavelets, etc)
- Allow processes in Python and Java

- Reproduce other tutorials / examples
- Change the graphic renderer from Matlab
Add FieldTrip functions:
- ft_sourceanalysis:
- Check noise covariance

http://www.sciencedirect.com/science/article/pii/S1053811916304232- ICA:
- Why doesn't the ICA process converge when using 25 components in the EEG tutorial?
- Add an option to resample the signals before computing the ICA decomposition
- Add a stand-alone tutorial
- Exploration: Add window with spectral decomposition (useful for muscle artifacts)
- Export IC time series (and then compute their spectrum): solves the problem above
Comparison JADE/Infomax:
http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0030135- Use faster methods (MNE-Python?)
- Add methods: SOBI, Fastica, AMICA/CUDICA (recommended by S Makeig)
Dimension reduction with PCA adds artifacts: Not done by default in EEGLAB
Contact: Stephen Shall Jones ( shall-jones@infoscience.otago.ac.nz )
Student Carl Leichter detailed this in his thesis- S Makeig: Use ICA to select the IC of interest instead of only removing artifacts
- Display of spectrum for components (PSD/FFT)
- Use FastICA (algo crashing)
- Add components preselection: Correlation with EOG/ECG
- Import ICA matrices available in EEGLAB .set files
EEGLAB recommends ICA + trial rejection + ICA again: Impossible right now with Brainstorm
(http://sccn.ucsd.edu/wiki/Chapter_09:_Decomposing_Data_Using_ICA)ICA+machine learning: https://www.ncbi.nlm.nih.gov/pubmed/28497769
Automated artifact rejection: https://arxiv.org/abs/1612.08194
- Save IC time series in database
Use EYE-EEG: EEGLAB toolbox for eye-tracker guided ICA (Olaf Dimigen): http://www2.hu-berlin.de/eyetracking-eeg/
- Other EEGLAB functions:
Step function detection: https://github.com/lucklab/erplab/wiki/Artifact-Detection:-Tutorial
- SSP:
Display warning if changing the ChannelFlag while there is a Projector applied
Show where the attenuation is projected:
(sum(IK,2)-sum(SSP(k,:)*IK,2)./sum(IK,2)
- Pipeline editor:
- When computing sources from the pipeline editor: doesn't reselect the options if you click twice on "edit" (works for minnorm, but not for lcmv)
- When computing time-frequency/hilbert/psd: Find a way not to force the user to click on Edit
- Bandpass:
- Use new filters in all the functions using a bandpass ('bst-hfilter' instead of 'bst-fft-fir'): process_evt_detect_threshold
- Weird bug: Filter(import) != Import(Filter) in the HCP tutorial... to investigate
- Bandpass
- Spectral flattening (John):
- ARIMA(5,0,1): Apply on the signal before any frequency/connectivity/PAC analysis
- PSD:
- Rewrite to have the same input as coherence (frequency resolution instead of window length)
- Use the progress bar
Allow display of Avg+StdErr
Remove line noise: http://www.nitrc.org/projects/cleanline
- Use Matlab Coder to optimize some processes: Wavelets, bandpass filter, sinusoid removal
- Reports: Click on link reopens exactly the figure
- Time-frequency:
- Optimization: bst_timefreq (around l.136), remove evoked in source space: Average should be computed in sensor space instead of source space (requested by Dimitrios)
Short-time Fourier transform: http://www.mikexcohen.com/lectures.html
Matching pursuit: http://m.jneurosci.org/content/36/12/3399.abstract?etoc
- Bug: Display logs as negative
- Bug: 3D figures: Colormaps with "log" option doesn't work
- Bug: Difference of power displayed in log: problems (Soheila)
- 2D Layout in spectrum
- Make much faster and more memory efficient (C functions coded by Matti ?)
- TF scouts: should display average of TF maps
- Impossible to keep complex values for unconstrained sources
- Pad short epochs with zero values for getting lower frequencies
- Hilbert with time bands very slow on very long files (eg. 3600s at 1000Hz) because the time vector is still full (10^7 values): save compressed time vector instead.
- Extend clusters tab to display of TF to overlay TF signals (Svet)
- When normalizing with baseline: Propagate with the edge effects marked in TFmask
- Allow baseline normalization of files computed with time bands
- Allow running TF on montages
- Review continuous files in time-frequency space (for epilepsy)
- Bug when computing TF on constrained and unconstrained scouts at the same time (in mixed head models for instance): uses only the constrained information and doesn't sum the 3 orientations for the unconstrained regions.
- Artifact detection:
- Artifact rejection like SPM: if bad in 20%, bad everywhere
- Test difference between adjacent samples
- Events detection: Add option "std" vs "amplitude"
- Co-registration of MEG runs:
- SSP: Group projectors coming from different files
- Finish validation of the method

Database
- Faster DB searches (for Emily)
- Add buttons to sort files: by name, by comment, by date
- MEG protocols: More flexible organization of the database; sub-conditions to allow different runs X different conditions.
- Matrix files: Allow to be dependent from other files
- Add notes in the folders (text files, visible as nodes in the tree)
- Screen captures: save straight to the database
- Rename multiple files
- Default headmodel lost when reloaded: Keep selection on the hard drive (in brainstormstudy.mat)
- Auto-save:
protocol.mat can be too big: do not store the results links in it (and recreate when loading)- http://neuroimage.usc.edu/forums/t/abnormally-slow-behavior/2065/10
- Improve auto-save: add tracking file next to protocol.mat, do not save all the time, only when closing app, and reload protocol at stratup if tracking file is still there

Various initiatives: http://samirdas.github.io/Data_sharing.html#/
Source modeling
- Project sources: Very poor algorithm to project sub-cortical regions and cerebellum (algorithm to fit surfaces should be imrpoved)
Menu head model > Copy to other conditions/subjects (check if applicable first)
Menu Sources > Maximum value: Doesn't work with volume or mixed head models
Mixed head models:
- Set loose parameter from the interface
- Volume grid:
- Optimize: 3D display (better than 9x9 cubes)
- Optimize: vol_dilate (with 26 neighbors)
Menu Sources > Simulate recordings:
- Do not close the 3D figures after generating a new file

- Noise covariance matrix:
- Display with figure_image()
- Storage of multiple noise covariance matrices (just like the head models)
- Always save as full, then at inversion time, we can decide between full, heteroskedastic (diagonal) or homoskedastic (i.i.d, scalar)
Problem of having inividual trials + averages in the condition => Display warning or not?
- Save nAvg in noisecov file, to make it easier to scale to other recordings
Sources on surface: Display peak regions over time (time = color) => A.Gramfort
Calculate ImagingKernel * Gain for a scout
- Time-frequency beamformers:
- Band-pass everything in different frequency bands + Source estimation + TF
- Ask data to Sarang where he sees effects that cannot be extracted with MN followed by TF
- Process "Extract scouts time series": Add PCA option (replace isnorm with choice PCA/Norm)
- BEM: Fix unstable results when one vertex is too close from the layers (5mm ?)
- Hui-Ling beamformers:
- More explanations about what is in NAI and Spatial filters
Explain that is this is better to study effects extended in time (Ntime > Nsensors)
- Group LCMV+MCB
- Condition LEFT median nerve: very bad results
- Keep options for inverse computation
- OpenMEEG: Post example datasets for the remaining issues:
- Example protocol ECOG: doesn't work
- Add eyes models to attract eye activity
Anatomy
BrainVISA: Add support for MarsAtlas
- MNI transformation: Use non-linear MNI transformation y_...
Registration:<<BR>>
Getting electrode positions from 3D scanners: https://sccn.ucsd.edu/wiki/Get_chanlocs
Use the same registration for multiple recording sessions that have already re-registered previously (eg. with MaxFilter)
- When linking multiple EEG recordings including 3D positions, do the registration only once and copy it to all the runs
- Check templates: MNI transformation and volume atlases for ICBM152 vs Colin27 (loading the AAL atlas as surface or voume scouts do not align well on the ICBM152)
- Compute non-linear MNI registration instead of linear
- Select and remove bad digitized head points before automatic coregistration
Load the MNE -transf.fif: http://neuroimage.usc.edu/forums/showthread.php?2830
- MRI Viewer:

- Pan in zoomed view (shift + click + move?)
- Zoom in/out with mouse (shift + scroll?)
- Ruler tool to measure distances
- Add keyboard shortcuts to scroll in the three orientations (same in MRI 3D)
- Display scouts as additional volumes
- Render surface envelope in the MRI as a thin line instead of the full interpolation matrix
- Edit fiducials: Replace 6 text boxes with 1 for easy copy-paste (see fiducials.m)
Optimize computation interpolation MRI-surface (tess_tri_interp) => spm_mesh_to_grid
BrainSuite:
Add new labels to all BrainSuite anatomy templates
Use BrainSuite inner skull for surface generation
- Use same colors for left and right for anatomical atlases
- Scouts:
- Display edges in the middle of the faces instead of the vertices
- Display scouts in a tree: hemisphere, region, subregion
- Sort scouts by region in process options
- Downsample to atlas: allow on timefreq/connect files
Project from one hemisphere to the other using registered spheres/squares (http://neuroimage.usc.edu/forums/t/how-to-create-mirror-roi-in-the-other-hemisphere/5910/8)
- Parcellating volume grids: scikit-learn.cluster.Ward
- Major bug when importing surfaces for an MRI that was re-oriented manually
- Smooth surface: Fix little spikes due to irregularities in the mesh
Surface>Volume interpolation: Use spm_mesh_to_grid
- Bug: Hide scouts in the preview of the grid for volume head models
ECOG/SEEG
- Electrode models: Better way for managing/updating/adding electrode models
SEEG: Project contacts to SEEG / Compare with IntrAnat
Contact positions: Import / set / detect
- New option: Align on none|inner|cortex to replace ECOG-mid

- Project contact positions across subjects or templates (Marcel)
- ECOG: Default names of contacts?
- Add menu to import implantation channel file in imported recordings
- Automatic segmentation of CT:
- ECOG:
- Project and display contacts on cortex surface should consider the rigidity of the grids: Contacts cannot rotate, and distance between contacts should remain constant across runs
Method for contacts projection: https://pdfs.semanticscholar.org/f10d/6b899d851f3c4b115404298d7b997cf1d5ab.pdf
ECOG: Brain shift: When creating contact positions on a post-implantation image, the brain shift should be taken into account for creating images of the ECOG contacts on the pre-op brain => iELVis (http://ielvis.pbworks.com/w/page/116347253/FrontPage)
- Display:
- Bad channels: Contacts greyed out instead of ignored (Marcel)
- Display time in H:M:S
- Display curved SEEG electrodes
- Display wires for ECOG?
- Re-referencing:
- Create new average reference montages with a specific list of channels, with the possibility to edit the order of the channels (for Jeremy)
- Closest white reference (Arnulfo)
Detection CEEP stim artifacts: Use ImaGIN code ImaGIN_StimDetect
Alternatives to OpenMEEG: SimBio/FieldTrip? Matti Stenroos? NFT/NIST?
Statistics
- ANOVA:
- Use LENA functions(?)
- Output = 1 file per effect, all grouped in a node "ANOVA"
- Display several ANOVA maps (from several files) on one single figure, using a "graphic accumulator", towards which one can send any type of graphic object
- New process to test for Gaussianity using swtest
- Simulate recordings with specific properties, for stat validation
Quality control before statistics, on condition averages across subjects:
mean(baseline)/std(baseline): shows bad subject quickly.Use SurfStat: Impements interesting things, like an analytical cluster-based p-value correction (Random-field theory which is used in SPM) - Peter
Input / output
XDF import: Use the EEGLAB plugin, contact Martin Bleichner (Oldenburg)

- Reference gradiometers: Keep the orientation of the first or second coil?
- Reference gradiometers: Add the sensor definition from coil_def.dat
- Validate with phantom recordings that noise compensation is properly taken into account
- References at too far from the head sensors in Marseille 4D system
- The noise compensation is considered to be always applied on the recordings, not sure this assumption is always correct
- 4D phantom tutorial (JM Badier?)
- EEG File formats:
EEG CeeGraph
- EGI: Finish support for epoched files (formats 3,5,7)

- 2DLayout:
- (TF) Units are weird with % values
- (TF) Difficult to navigate in frequencies: Scaling+changing frequency resets the scaling
- Progress bar:
- Doesn't close properly on some Linux systems
- Focus requests change workspace when processing constantly (Linux systems)
- MacOS bugs:
- Buttons {Yes,No,Cancel} listed backwards
- Record tab: Text of epoch number is too big
- Colormap menus: Do not work well on compiled MacOSX 10.9.5 and 10.10
- Matlab bugs:
- Interface looks small on screens with very high resolutions: Reduce the resolution
- Event markers are not visible anymore with the sequence: Open MEG, open EOG, close MEG
- in_bst_data_multi: If trials have different sizes, output is random (the one of the first file)
- Edit scout in MRI: small modifications cause huge increase of the scout size
- Canolty maps computation: Fix progress bar
Geeky programming details
- bst_bsxfun: After 2016b, we can use directly the scalar operators (./ .* ...) instead of bsxfun. Update bst_bsxfun to skip the use of bsxfun when possible.
Interface scaling: Rewrite class IconLoader to scale only once the icons at startup instead of at each request of an icon (might improve the speed of the rendering of the tree)
- Hide Java panels instead of deleting them
- Processes with "radio" and "radio_line" options: Replace with "radio_label" and "radio_linelabel"
- Interpolations: Use scatteredInterpolant, griddedInterpolant, triangulation.nearestNeighbor (2014b)
- bst_warp and channel_project: Use tess_parametrize_new instead of tess_parametrize
- Shared kernels: "get bad channels" operation in a different way (reading all the files is too slow)
- Optimize bst_get:
- Now study and subject have necessarily the same folder name
- Replace big switch with separate functions
- Progress bar:
- Add different levels (to handle sub-processes)
- Make work correctly with RAW on resting tutorial
- Uniformize calls in bst_process/Run
- Add a "Cancel" button
- Fix all the 'todo' blocks in the code
- Error message: Add a link to report directly the bug on the forum
