When I specified a model with SPM5 and start the model estimation, I get following error messages: -------------------------- Running "fMRI model estimation" ??? Undefined command/function 'spm_list_files'. Error in ==> spm_config_fmri_est>run_est at 381 [j,unused] = spm_list_files(pwd,files{i}); Error in ==> spm_jobman>run_struct1 at 1379 feval(prog,val); Error in ==> spm_jobman>run_struct1 at 1387 run_struct1(c.val{i}); Error in ==> spm_jobman>run_struct1 at 1387 run_struct1(c.val{i}); Error in ==> spm_jobman>run_struct at 1346 run_struct1(c); ??? Error while evaluating uicontrol Callback. >> -------------------------- I found that spm_list_files.m and the associated other files are missing in the SPM5 directory. I copied the old spm_list_files.* files from my old SPM5b directory, now the model estimation works fine. The files missing in the SPM5 package are: spm_list_files.mexglx spm_list_files.mexsol spm_list_files_expand.m spm_list_files.dll spm_list_files.m spm_list_files.mexa64 Is this workaround necessary?
