Hi Carlo

that command line loads a volume, not a surface. Do you load the surface from the interface? You can do it from the command line with -f <surface name>. Not sure about your problem, but we'll need more details about what you did

Dear FreeSurfer experts,

I'm sorry but I have another problem..now when I load a surface (freeview -v OAS2_0001_MR1.long.OAS2_0001/mri/norm.mgz)Freeview starts but i can't see t he image and only when I change for example values in opacity or window, th e image appears but immediately disappears. I forgot to say that i'm using u buntu 11.10 64 bit. (FreeSurfer v5.1.0 on ubuntu 11.10

on a notebook ASUS i3-350M, 4GB RAM and ATI Mobility RadeonHD 5470 1GB RAM D DR3)

Thanks Best regards Carlo Cotugno

I'm a newbie with FreSurfer and Linux. I'm following Longitudinal Processing-Tutorial. now I have only files of tutorial data set and I don't have any other file to test. I can run Freeview and I can load volume from terminal and from interface, but when I try to load surfaces (from terminal with correct command -f OAS2.... or from interface of Freeview) I have the same result: Freeview interface crashes and in the terminal I find: MatrixMultiply: m2 is null! No such file or directory.

I tried also with other surfaces and I had the same result. F http://www.wordreference.com/enit/furthermoreurthermore when I installed long-tutorial in $FREESURFER_HOME/subjects directory the directory long-tutorial was with another owner and I had to change owner with command "chown -R", or I couldn't use it. I tried also to remove the directory and reinstall long-tutorial but the problem of owner still remains and I had to run "chown -R" in order to have access to the directory and its files. I followed instructions to the letter but now I don't really know how to fix it.

sorry for my english thanks
