Hi Amanda
mris_convert -c lh.thickness.asc lh.white lh.thickness.mgz
should do the trick cheers Bruce On Mon, 15 Oct 2018, Worker, Amanda wrote:

How would I do that? mris_convert doesn't seem to take .asc as an input?

Can you use mris_convert to convert the asc back to a curv file?

Hello,
I am trying to overlay a .asc file in either freeview or tksurfer, but so far having no luck.
As practice and to determine the right format, I am simply using lh.thickness, which I've converted to .asc using the following command:
% mris_convert -c lh.thickness lh.white lh.thickness.asc
I am trying to overlay this onto lh.pial for one subject, however I cannot load the file and I get the following error message:
% mri_read(): couldn't determine type of file /data/project/biobank/normative_modelling/DATA/03129b39-45a0-4491-9fdf-c7062a631d19/surf/lh.thickne
ss.asc
surfer: couldn't load /data/project/biobank/normative_modelling/DATA/03129b39-45a0-4491-9fdf-c7062a631d19/surf/lh.thickne
ss.asc.
If you were trying to load a functional volume, make sure you selected the right registration method, and if necessary, that the registration file exists. If you were trying to load a volume-encoded value file, make sure it has the same number of values as this surface does vertices (128970). sclv_read_from_volume: error in FunD_New
Interestingly, I can load the file as a curvature file, but then can't play around with the threshold.
Do you have any idea what I'm doing wrong? Any help would be appreciated!
Thanks,
Amanda
