Dear SPMers,
I have some further information. Basically, the SPMcfg.mat file
was saved after I specified the model. Now, when I hit the "Estimate"
button in SPM, I select the SPMcfg.mat file, but I still get the same
error as before, which reads:
SPM99: spm_spm (v2.37) 15:17:55 - 22/03/2000
========================================================================
Initialising design space :
...computing ...F-contrast ...done
Output images :
...initialising ...initialised
Plane 1/24 , plank 1/1
: ...read & mask data??? Cant
open image file.
Error in ==> \\Ccnserv1\programs\matlab\spm99\spm_sample_vol.dll
Error in ==> \\Ccnserv1\programs\matlab\spm99\spm_spm.m
On line 703 ==> Y(i,CrLm) = spm_sample_vol(VY(i,1),...
%-Load data in mask
??? Error while evaluating uicontrol Callback.
Does anyone know what could be causing this ubiquitous error?
Thanks,
Daniel Weissman
