Simulations: https://github.com/lrkrol/SEREEGA

Interface

Add a warning when computing a forward model with > 100000 sources (check selection)
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
- Global colormap max: Should get the maximum across all the open files
Copy figures to clipboard (with the screencapture function)
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
Progress bar: Add a "Cancel" button
Error message: Add a link to report directly the bug on the forum
Reorganize menus (Dannie's suggestion):

Connectivity

Thresholding and stat tests for 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)
Connect NxN display:
- Graph on sensors: does not place the sensors correctly in space
- Display as image: Add legend of the elements along X and Y axis
- Display as time series: Display warning before trying to open too many signals
- Optimize display: use surface() instead of line() for links? (as in figure_3d/PlotFibers)
Time-resolved correlation/coherence: Display as time bands
Weighted Phase Lag Index (WPLI)
Coherence: Average cross-spectra instead of concatenating epochs (to avoid discontinuities)
Explore inter-trial approaches (Esther refers to chronux toolbox)
Granger: Check for minimum time window (Esther: min around 500-1000 data points)
PLV:
- Remove evoked
- Add time integration
- Unconstrained sources
- Add warning when running of short windows (because of filters)

Processes

Plugin manager:
- Export all the software environment to a .zip file (brainstorm + all plugins)

- Change the graphic renderer from Matlab
Add FieldTrip functions:
- ft_sourceanalysis:
  - Check noise covariance
  - Check all the options of all the methods
  - Single trial reconstructions + noise covariance?
  - Filters?? http://www.fieldtriptoolbox.org/example/common_filters_in_beamforming
  - Beamformers: Save ftSource.avg.mom
    http://www.fieldtriptoolbox.org/workshop/meg-uk-2015/fieldtrip-beamformer-demo

Optimization:
- Use CUDA for speeding up some operations (filtering, wavelets, etc)
- Use Matlab Coder to optimize: Wavelets, bandpass filter, sinusoid removal
Pipeline editor:
- Bug: After "convert to continuous", the time of the following processes should change
- Add loops over subjects/conditions/trial groups
- Events: Allow selection from a drop-down list (similar to option "channelname" in panel_process_selection)
ITC: Inter-trial coherence (see MNE reports for group tutorial)
http://www.sciencedirect.com/science/article/pii/S1053811916304232
ICA:

- Comparison JADE/Infomax:
  http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0030135
- 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
- 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
Remove line noise: http://www.nitrc.org/projects/cleanline
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
- 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.
- 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.

Source modeling

Unconstrained sources:
- Unconstrained to flat: Default PCA for stat and connectivity?
- Process "Scouts time series": Add PCA option (replace isnorm with radio PCA/Norm)

MRI Viewer:
- Pan in zoomed view (shift + click + move?)
- Zoom in/out with mouse (shift + scroll?)
- Ruler tool to measure distances
- Display scouts as additional volumes
- Render surface envelope in the MRI as a thin line instead of the full interpolation matrix
  Or use inpolyhedron to get a surface mask and then erode it to get the volume envelope

Parcellating volume grids: scikit-learn.cluster.Ward
Geodesic distance calculations:
https://www.mathworks.com/matlabcentral/fileexchange/6110-toolbox-fast-marching

ECOG/SEEG

Contact positions: Import / set / detect
- New option: Align on none|inner|cortex to replace ECOG-mid
- Project contact positions across subjects or templates (Marcel)
Create clusters from anatomical labels:
- Identify contacts in a given anatomical region (volume scout, surface mesh, or label in a volume atlas) / allow extracting the signals from all the contacts in an ROI
Automatic segmentation of CT:
- GARDEL: http://meg.univ-amu.fr/wiki/GARDEL:presentation
- SEEG DEETO Arnulfo 2015: https://bmcbioinformatics.biomedcentral.com/articles/10.1186/s12859-015-0511-6
  - Used routinely at Niguarda Hospital + other hospitals worldwide, reliable tool.
  - To be used with SEEG-assistant/3DSlicer: https://bmcbioinformatics.biomedcentral.com/articles/10.1186/s12859-017-1545-8

- SEEG Granados 2018 (no code shared): https://link.springer.com/content/pdf/10.1007/s11548-018-1740-8.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)
- Display time in H:M:S
- Display curved SEEG electrodes
Detection CEEP stim artifacts: Use ImaGIN code ImaGIN_StimDetect

Statistics

Stat on connectivity?
Stat on unconstrained sources?
