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

Time-resolved correlation/coherence: Display as time bands
Weighted Phase Lag Index (WPLI)
Coherence: Average cross-spectra instead of concatenating epochs (to avoid discontinuities)

- 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

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)
Reproduce results in "Simultaneous human intracerebral stimulation and HD-EEG, ground-truth for source localization methods": https://www.nature.com/articles/s41597-020-0467-x

BEM single sphere: Get implementation from MNE
Volume grid:
- Optimize: 3D display (better than 9x9 cubes)

- FastSurfer: https://deep-mi.org/research/fastsurfer/
MNI normalization: More options:
- DARTEL / SHOOT
- BrainSuite (wait for Anand)
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
- Surface>Volume interpolation: Use spm_mesh_to_grid instead of tess_tri_interp
Defacing:
- https://afni.nimh.nih.gov/pub/dist/doc/htmldoc/tutorials/refacer/refacer_run.html
- Removing MNI face mask using MNI coordinates
Atlas switch in 3D MRI figures
ICBM152 update:
- Process with FreeSurfer 7.1 + add FS atlases (Brainnettome, Schaeffer, HCP...)
- Add volume atlases (+ reimport ASEG as volatlas)
- Add facemask => Use for defacing with any MNI registration
- Add T2?
BrainSuite:
- Use same colors for left and right for anatomical atlases

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
- ECOG Centracchio 2021: https://link.springer.com/content/pdf/10.1007/s11548-021-02325-0.pdf
  - Classifier on thresholded CT: https://github.com/Jcentracchio/Automated-localization-of-ECoG-electrodes-in-CT-volumes
- 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?
ANOVA:
- Write panel similar to Process1 and Process2
- 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

Processes with "radio" and "radio_line" options: Replace with "radio_label" and "radio_linelabel"
Interpolations: Use scatteredInterpolant, griddedInterpolant, triangulation.nearestNeighbor (2014b)

-Line 72:
+Line 112:
-  * Make average the default option
-Line 74:
+Line 113:
-  * Show where the attenuation is projected:<<BR>>(sum(IK,2)-sum(SSP(k,:)*IK,2)./sum(IK,2)
 * Bandpass:
  * Rewrite without the force low-pass filter at Fs/3
  * Show warning when using inappropriate high-pass filter (precision too high)
  * Use FIR filter
 * Spectral flattening (John):
  * Apply on the signal before any frequency/connectivity/PAC analysis
  * Using ARIMA(5,0,1)
  * Example code:<<BR>><<BR>>
  {{{
arm = mean(lpc(diff(detrend(Fbase')),5)); % detrend and diff
PRE = filter(arm,1,diff(detrend(Fbase')))'; % apply to the data|
X = filter(arm,1,diff(detrend(F')))';
X(:,1:length(arm)) = [];
Time = tndx((length(arm)+2):end)/1000 - SOT;
}}}

 * PSD:
  * Estimation of the output size buggy
  * Rewrite to have the same input as coherence

- * Interpolate the bad channels
 * ICA for cleaning eye movements in EEG low density (SSP don't work well)
 * Band-limited power envelope
 * Reports:
  * Save as HTML / PDF

  * Display standard deviation as a halo around the time series
 * Co-registration of MEG runs:

== Database ==
 * Optimize startup speed
 * Start Brainstorm without Java (-nodesktop)
 * Sort files by comment
 * MEG protocols: More flexible organization of the database; sub-conditions to allow different runs X different conditions.
 * Group matrix files => allow to process matrix files by trial types

 * Add notes in the folders (text files, visible as nodes in the tree)

 * Screen captures: save straight to the database

 * Rename multiple files

 * Allow matrix files to be attached to other files
+  * 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.
