Trying to start fMRI-CPCA (v 8.3.03_Jun_2012) on a Windows 7 machine (Matlab v 7.11.0.584 R2010b) was unsuccessful due to an error originating in check_memory.m if the current working directory is a network path.

Line 34 ("xx = evalc(cmd);") produced this output:  

'\\tower3\home16\naf36\MATLAB' 
CMD.EXE was started with the above path as the current directory. 
UNC paths are not supported.  Defaulting to Windows directory. 
Total: 8243 Avail: 586  

...resulting in the following line ("stats.user.total=sscanf( char(xx), '%*s%d%*s' );") returning an empty array, which then produces an error in update_memory_stats at line 1224.

My quick fix was to add the following lines after line 24 in check_memory.m:

    oldpwd = pwd;
    cd(mck);and this line before the end of the "if ispc" block:    cd(oldpwd);
