Hi All,

I?ve tried to convert w file into niifi format for mrVista by using the following code, and got "w file vertex number out of range.? message from mne_volume_data2mri. Does anyone know the meaning of this message?

(I used ico 5 for both source space and forward model.)

Here is the code I used:

mne_volume_source_space --mindist 3 --surf $SUBJECTS_Anatomy_DIR/$SUBJECT/surf/lh.sphere --bem $SUBJECTS_Anatomy_DIR/$SUBJECT/bem/$SsFileHead-bem.fif --mri $SUBJECTS_Anatomy_DIR/$SUBJECT/mri/T1.mgz --src $Data_DIR/$SUBJECT/$SsFileDir/$SsFileHead-vol-lh-src.fif

mne_volume_data2mri --scale 0.1 --src $Data_DIR/$SUBJECT/$SsFileDir/$SsFileHead-vol-lh-src.fif --w $Data_DIR/$SUBJECT/$SsFileDir/$SsFileHead-w-$PickTimeFileName-lh.w --out $Data_DIR/$SUBJECT/$SsFileDir/$SsFileHead-$PickTimeFileName-lh.w.mgz

Thanks,
Sanyuan

hi Sanyuan,

ico5 refers to a surface/cortical source space. Could it be the issue
as you want to manipulate volume grids?
