Hi
For one of my subjects I need to swap some of the channel names. The data was collected using BioSemi 128 channels. Some of the channels are labelled erroneously in the raw file and this remained after creating the link to raw file in Brainstorm. Is there a way to do this (swap the channels currently listed as D1-D32 with those listed as C1-C32 in Brainstorm)? Is this an option either in Brainstorm or via scripting in Matlab?
You can't change the order of the signals in the raw files, but you can rename the channels in the channel file.
- From the interface: Right-click on the channel file > Edit channel file > Rename the channels, save the modified channel file.
- Modifying the channel structure manually: right-click on the channel file > Export to Matlab, modify the fields .Channel(i).Name from the Matlab command window, right-click on the channel file > Improt from Matlab

- Same as #2 but modify the structure directly in the .mat file with the load/save functions in Matlab
