hou could do it easily enough in matlab with read_label.m and write_wfile.m, but as Doug says, w files are a goofy format that we never use anymore.

Not sure. We are trying to get away from .w files for this reason. Can you use something other than a w file?

Thank you Doug that worked perfectly.
Is it possible then to go back to a .w from a label?

Use mri_surf2surf to convert it to an mgh or mgz file, then use mri_cor2label with the --surf option to convert it to a label

Hi Bruce and Freesurfer developers,
Thank you. Any suggestions on converting a binary .w file to a label would be very helpful.
Best, Derek

Hi Derek
I'll cc the FS list so others can answer. It depends on the reason the holes exist. It also depends on the size of the holes. The dev version of mri_label2labels supports morphological close operations. It takes an integer parameter which should be about the radius of the holes you would like to fill in. Note that this will also fill in some concavities in the boundary of the label.
cheers Bruce

Hi Bruce,
Apologies for contacting you directly but I’m not sure if my message is getting through to the list.
I have gotten ahold of the dev version of mri_label2label.
Currently I have a .w file that I need to “fill in the holes” on. Could you please specify the steps I will need to take to make my .w file an acceptable input for mri_label2label, and any recommendations you may have for the value of N for the —close flag.
Any help you could provide would be appreciated.
Best, Derek
