Hello I wonder if any of you could hazard a guess at what seems to be wrong. Since I downloaded and installed revision 826, I have been having 2 different problems, neither of which occurred before the update. *********************************************** 1) Realign no longer works. The error message is...... ??? Error while evaluating uicontrol Callback. ??? Undefined function 'realign_unwarp'. 2) When setting up 1st and 2nd level analyses, when I try to save the jobfile over the old one, it won't. The following error message is produced ..... D:\Program Files\MATLAB6p5\work ??? Error using ==> strfind Inputs must be character arrays. Error in ==> d:\program files\spm5\spm_jobman.m (save_job) On line 1423 ==> extind = strfind(cll(:,1),defext); ??? Error while evaluating uicontrol Callback. ***************************************** If it has any bearing, we are still on matlab version 6.5, release 13.01 Hoping you can help Rachel -------------------------------------------------------- Dr Rachel L.
