finished) ==== Documentation ==== * Cross-validation with MNE and FieldTrip (work in progress): <<BR>>http://martinos.org/mne/dev/auto_tutorials/plot_brainstorm_auditory.html * New tutorial: MEG resting-state / OMEGA database ==== Functional connectivity ==== * Significance thresholding of the connectivity matrices (not started) ==== Computation ==== * Removing the dependence to the Java interface to run in headless mode (not started) * Call MNE-Python and FieldTrip functions from Brainstorm GUI (work in progress) <<BR>><<BR>> == Recordings == * RAW file viewer: * '''Faster display''': Downsample time series before plotting * 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.<<BR>>Example: http://www.erpinfo.org/erplab/erplab-documentation/manual/Binlister.html * 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: * Overlay multiple conditions * Does not work when DC offset is not removed == Interface == * Start Brainstorm without Java (-nodesktop) * Option to increase the size of all the elements of the interface (for high res laptop screens) * 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 * Open new figures as tab (docked in the Figures window) * Copy figures to clipboard (with the screencapture function) * Removing all the CTRL and SHIFT in the keyboard shortcuts * Display warning before opening files that are too big * Smooth display from figure_image (ERPimage, raster

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?
- Graph view:
- Does not display negative values correctly (correlation or difference of coherence)
- Re-write using pure Matlab code and smoothed graphics
- 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
- Disable zoom in one region (serious bugs)
- NxN on sensors: does not place the sensors correctly in space
- Coherence:
Average cross-spectra instead of concatenating epochs (to avoid discontinuities)
Explore inter-trial approaches (Esther refers to chronux toolbox)
- Granger:
- Crashes sometimes: improve stability
- Check for minimum time window (Esther: min around 500-1000 data points)
- Re-write and optimize code

- ICA:
- 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- 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)
- Understand why EEG/Epilepsy tutorial data crashes if we don't limit the number of components
- 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)
- 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
- SSS/tSSS: Get implementation from MNE
- Bandpass: Use new filters in all the functions using a bandpass ('bst-hfilter' instead of 'bst-fft-fir')

- 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 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
- Apply to continuous recordings for correcting head movements
- Other processes:
- Moving average
- Max
- Median
- Simulation:
Fix units in simulation processes => no *1e-9 in "simulate recordings"

- Use field process field "Group" to separate Input/Processing/Output options
- Use new Matlab functions: movmean, movsum, movmedian, movmax, movmin, movvar, movstd
- Process ft_prepare_heamodel: Add support from BEM surfaces from the Brainstorm database
Database
- 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.
- Navigator: Use F2/F3 to explore the entire database (right now F2 works in a weird way)
- 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)
- protocol.mat can be too big: do not store the results links in it (and recreate when loading)

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

- Compute non-linear MNI registration instead of linear
- MRI Viewer:
- Add keyboard shortcuts to scroll in the three orientations (same in MRI 3D)
- Display scouts as additional volumes

- ECOG: How to handle cases where not all the grid contacts are in the channel file? (Marcel)
- Project contact positions across subjects or templates (Marcel)
- Display:
- Display SEEG+ECOG contacts at the same time
- Better way to represent ECOG strips that are not in contact with the skull (new type?)
- SEEG length: count from the most superficial contact
- SEEG default view: transparent cortex instead of MRI viewer (Marcel)
- ECOG: Project on cortex instead of inner skull, just for display (Marcel)
- Color each strip/grid differently
- Bad channels: Contacts greyed out instead of ignored (Marcel)
- ECOG: Topography display without the 3D coordinates (Marcel)
- 2DLayout: Should not try to use the actual position of the sensors, just the grids/strips.
- Display time in H:M:S
Alternatives to OpenMEEG: SimBio/FieldTrip? Matti Stenroos? NFT/NIST?
- Prepare tutorial with public dataset (Marcel)
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
- PLS: Partial Least Squares
- 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
