Segmenting an .img attached file using: cfg.coordsys = 'ctf'; gives the ctfSegmentation.jpg attached which has missed the frontal area but using cfg.coordsys = 'spm'; gives the spmSegmentation.jpg attached which provides the expected segmentation.

no pictures attached. Note: could be user error, from the previous bugs filed it seems the coordsys should be 'neuromag' to begin with (assuming the image has been registered)

Created attachment 427 segmented MRI using ctf and spm

I attached the file again. Could be my error, but I don't use any MEG and just segment the mri using 'ctf' and 'spm'

this is probably a user error. please read the relevant tutorial documentation about coordinate systems etc and doing segmentations in fieldtrip. Your anatomical MRI needs to be registered in a coordinate system that fieldtrip understands. If it is already MNI, then coordsys= 'spm'.

This closes a whole series of bugs that have been resolved (either FIXED/WONTFIX/INVALID) for quite some time. If you disagree, please file a new issue describing the issue on
