Current bugs
- Workshops:
- Create scouts doesn't work: scout created on the other side of the brain
- Import anatomy folder: Out of memory sometimes (restart Matlab)
- Bandpass filter: Out of memory (Auditory workshop)
- Bug workshop Michael (Mint 12/gnome3/linux 3.0.0-12, KWin/Mutter/Compiz)
- Cannot import two .ds folders at once
- Colors inverted in the PSD/TF plots (power vs. log)
- Cannot type the name of a channel in "Detect ECG"
- Smooth TF windows that contain multiple plots
- Record tab: Text of epoch number is too big on MacOS
- in_bst_data_multi: If trials have different sizes, output is random (the one of the first file)
- tree_dependencies: sources files, reprojected on default anatomy; If based on data files that are bad trials, they should be ignored by tree_dependencies, and they are not
- Image viewer has some bugs on some systems
- Screen capture when there is a fading effect in the window manager: captures the window
- Close figure with coherence results should hide the "frequency" slider
- Edit scout in MRI: small modifications cause huge increase of the scout size
- Reports: Text size is too small with Java 1.5 (2006b-2007a)
- Optimize MRI viewer with patch() instead of image()
- Matlab 2014b bug with rmdir/movefile: Enter but never returns from the call
- 2DLayout (time series): Sometimes the lines are not visible
- 2DLayout (TF): Images are too far apart with EEG 20 channels
Geeky programming details
- Removing all the CTRL and SHIFT in the keyboard shortcuts
- Hide Java panels instead of deleting them
- mri2scs: convert arguments to meters
- Interpolations: Use scatteredInterpolant, griddedInterpolant, triangulation.nearestNeighbor (Matlab 2014b)
- 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)
- Optimize bst_get:
- Now study and subject have necessarily the same folder name
- Replace big switch with separate functions
- Progress bar:
- Add different levels (to handle sub-processes)
- Make work correctly with RAW on resting tutorial
- Uniformize calls in bst_process/Run
- Add a "Cancel" button
- Line smoothing / anti-aliasing (time series figures)
- Fix all the 'todo' blocks in the code
- Replace handle "0" with bst_get('groot')
- At the end of bst_startup in compiled mode, replace loop with waitfor(jFrame)
- Error message: Add a link to report directly the bug on the forum
in_bst_results (isFull=1): DataFile should be relative
