What's next
A roadmap to the future developments of Brainstorm.
Current topics

Recordings
- RAW file viewer:
- Pre-load next page of recordings
- Allow multiple RAW windows(columns display)
- Screen setups: save configuration of windows

- Documentation: Add definition of bad segments
- Set the amplitude scale for the time series
2DLayout: Doesn't work when changing page => need refresh of GlobalData.Preferences.TopoLayoutOptions.TimeWindow
EEG reference/storage:
- Intracranial electrodes: Define and display in the MRI viewer + 3D figures
- Re-reference recordings
- 2D topo plots: Display bipolar montages with electrodes positions = average of the two electrodes
- Bad locations: indicate with [NaN NaN NaN] instead of [0 0 0]
- Location of bipolar electrodes: Save the 2 positions in the channel file, with weights=[1 -1]
Bad channels that can be specified at the program level (for sites that have permanently bad channels) => AS Dubarry
- RAW processing:
- Make it work for all the file formats (at least bandpass filter + sin removal)
Events: advanced process for recombining. Example: http://www.erpinfo.org/erplab/erplab-documentation/manual/Binlister.html
Colormaps:
- Create a colormap similar to MNE, where extrema are bright
- Import data:
- Save properties "baseline" and "resample" at the level of the protocol (to re-use for all the files)
- NIRS:
- Add new data type
- Display of sensors by pairs oxy/deoxy (red/blue), overlaid
- Images of amplitude: [sensor x time], [trial x time], scout: [trial x time]
Can be done with Matrix > View as image: extract cluster, concatenate for all trials
- 2D Layout for multiple conditions
Connectivity
- Figures: interaction with sensor selection / scouts selections
- Display NxN as 1xN
- Adapt colormaps for correlation (min and max properties)
- PLV: Add a time integration

- Artifact rejection like SPM: if bad in 20%, bad everywhere
- Test difference between adjacent samples
- Distributed processing: Brainstorm that can run without Java
- SSP:
Display warning if changing the ChannelFlag while there is a Projector applied
- When processing multiple files: waitbar is not behaving well
- Improve interface for SSP on imported recordings
- Define SSP from one time point
Show where the attenuation is projected:
(sum(IK,2)-sum(SSP(k,:)*IK,2)./sum(IK,2)
- Average:
- Remember how many trials were used per channel
- Save standard deviation
- Display standard deviation as a halo around the time series
- 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
Current Source Density (CSD) => Ghislaine
http://psychophysiology.cpmc.columbia.edu/software/CSDtoolbox/index.html- Other processes:
- Detrending
- Moving average
- Max
- Median
- Significance test (Dimitrios, Leo)
- Spatial smoothing: check / document parameters
Contact sheets & movies: use average of time windows instead of single instants, for each picture.
- Optical flow
- Spectrum figure: use bst_selection
Database
- 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
Source modeling
- Stenroos 2014 paper: Include the following methods
Inner and outer skull surfaces generator from FieldTrip (needs SPM, probably not so different from BST)
- Nolte corrected-sphere model (good model re:Alex)
- Fast BEM models
- Dipole fitting
- Visualize Beamformer results (contact Zainab Fatima):
- Read CTF SAM .svl
- Create new file type in the database
- Display as layers in the MRI viewer
- Unconstrained sources:
- Compute unconstrained and then project on the normal ?
- Difference and stat should be: norm(A) - norm(B)
- Stat and connectivity: what to do? (re-send email John+Sylvain)
- Overlapping spheres: improve the estimation of the spheres for the frontal lobes
- Volume grid:
- Scouts 3D
- Test volume sources with all the subsequent processes (timefreq, stat...)
- Optimize: 3D display (better that 9x9 cubes)
- Optimize: vol_dilate (with 26 neighbors)
- Magnetic extrapolation:
- Do the same thing with EEG
- Noise covariance matrix:
- 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
When deploying to other conditions: Apply destination SSP (NoiseCov = SSP . NoiseCov . SSP' )
Sources on surface: Display peak regions over time (time = color) => A.Gramfort
- Simulation: synthesize pseudo data-files from a cortex patch (duration, amplitude, noise)
Calculate ImagingKernel * Gain for a scout
- EEG Source modeling: Manage references and bipolar montages properly (maybe not necessary)
- MEG source modeling: Do reconstruction only for a subset of sensors for estimating dipoles?

- Generate mixed density surfaces
- Import / registration:
- Major bug when importing surfaces for an MRI that was re-oriented manually
- Use mid-gray instead of pial surface?
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
- Permutation tests:
- t-test only (wilcoxon? sign-test?): paired, equal var, unequal var
- nb permutations ~ 1000
- maximum statistic over "time" or "time and space"
- Permutations / clustering: cf fieldtrip
Threshold in time: keep only the regions that are significative for contiguous blocks of time, or over a certain number of time points
=> Process that creates a static representation of a temporal window- t-test on volume sources
- Create icons for Stat/PAC, Stat/Sprectrum, etc.
- One sample t-test across subjects
Input / output

- Image viewer has some bugs on some systems
- Screen capture for reports never works: Find another solution
- Screen capture when there is a fading effect in the window manager: captures the window

Geeky programming details
- Use Matlab Coder to optimize some processes: Bandpass filter, sinusoid removal
- Hide Java panels instead of deleting them
- mri2scs: convert arguments to meters
- bst_warp and channel_project: Use tess_parametrize_new instead of tess_parametrize
- Shared kernels: do the "get bad channels" operation in a different way (reading all the files is too slow)
