Hi Francois,
Sorry I have another question,
If I write just the channel file (exported from BST to .pos file) in fiff file and then I load it again, does the info in coil_def.dat will integrated now?
or I need to write both the channel and raw file into fif file? because when I loaded an example from BST mind004_050924_median01_raw.fif as you see in the attached image both the raw and channel file appear
for this I think to save the both again in fif format, but may be it is enough just to save the channel file, and this will be more easy i think?
Thank you
