External Email - Use Caution        

Hello,

I am having an issue with the mri_label2label command.

What I did was mri merge of the BA4 a and p labels for each hemisphere from the fsaverage files, ending up with a lh.BA4.label and a rh.BA4.label.

I am wanting to now map the fsaverage lh.BA4.label and rh.BA4.label onto the individual subjects into my study, and was told that to do this, I needed to create those same labels using the BA4 a & p labels in the individual subject label file, and then run the command mri_label2label.

This is the command that I am running:

mri_label2label --srcsubject fsaverage --srclabel lh.BA4.label --trgsubject SRMC01_1.long.SRMC01 --trglabel lh.BA4.label --regmethod surface --hemi lh


And it keeps giving me this error message:


srclabel = lh.BA4.label

srcsubject = fsaverage

trgsubject = SRMC01_1.long.SRMC01

trglabel = lh.BA4.label

regmethod = surface


srchemi = lh

trghemi = lh

trgsurface = white

srcsurfreg = sphere.reg

trgsurfreg = sphere.reg

ERROR: could not read .//SRMC01_1.long.SRMC01/surf/lh.white

The lh.white file is definitely in the surface folder under that subject so I'm not sure why is says there is no such file or directory.


Any help would be greatly appreciated!!
