Hello @Raymundo.Cassani ans @chinmay.chinara, many thanks for your help and sorry for the delay in my replay, I was asked to work on another project for few weeks, back into my brainstorm analysis since few days.
I finally succeed (i believe) to convert my LPS coordinates system from 3D slicer into MNI Brainstorm system. I follow your procedure :
- Extract LPS coordinates from 3D Slicer
- Convert LPS into RAS coordinate (2 axes shifting)
- Convert from millimeter to meter my coordinates
- Use the matlab brainstorm fonction cs_convert(sMRI, ‘MNI’, ‘SCS’, MatrixCoordinates)
Electrodes seems to be on the right side and right place so i'am happy! Thanks it was not trivial.
I'm back with another challenge for my analysis... I just post it here : Mark epochs of interest from a list of timestamps extracted from matlab
if you still have energy to help!
Many thanks,
Florian
