Dear experts

I have a question regarding Freesurfer- LGI error I got during running LGI after all recon steps been ran with no problem. you could see the error below.

reading filled volume...

??? undefined function or variable 'ismac'.

error in -->load_mgh at 68

if(strcmp(computer,'MAC') || strcmp(computer,'MAC') || ismac)

error in -->MRIread at 87

[mri, voi, M, mr_parms, volsz] = load_mgh (fspec, [], [], headeronly);

error in --> make outer-surface at 24

vol = MRIread(filled_volume);

>> ERROR:make _outer_surface did not creat output file 'net/storage1/usr2/onrc/home/p2/Aahmadi/onrc/data/Aral-july/test/subject

Linux compute31 2.6.32-504.12.2.e16.*86_64 #1 SMP Wed Mar11 UTC 2015 86_64 86_64 GNU/Linux

recon-all -s S1091RPY existed with Errors at thu jan19 2017

The error is ...Undefined function or variable 'ismac' - matlab is expecting that variable to be defined (it's trying to detect the OS, whether Linux, windows/ Mac), but it isn't.

I appreciate if you give me your advice on this issue.

Thanks,

Aral
