What's next

A roadmap to the future developments of Brainstorm.

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

• Rename protocol

• 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/

  • https://www.youtube.com/watch?v=xAoljeRJ3lU

• 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

• 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?
• Matrix view of NxN graphs: Add legend of the elements along X and Y axis
• 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)

  • 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

  • Display of spectrum for components (PSD/FFT)
  • Use FastICA (algo crashing)
  • Add components preselection: Correlation with EOG/ECG

  • 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)

  • 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:

• 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

  • 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

  • MAP07 / SPM: https://www.epi.ch/_files/Artikel_Epileptologie/Huppertz_2_13.pdf

• 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)

• 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.

• Image viewer:
  • Difficult to get to 100%
  • Buggy on some systems

  • (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:

• 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
