Hi all, I am using Matlab r2014a and spm8, on my mac which is running Mavericks, and all of a sudden whenever I try to open SPM from my external hard drive which SPM has always been installed on. I receive the following errors: Loading of toolbox /Volumes/YUSUF'S HD/spm8/toolbox/DARTEL/._tbx_cfg_dartel.m failed. Loading of toolbox /Volumes/YUSUF'S HD/spm8/toolbox/FieldMap/._tbx_cfg_fieldmap.m failed. Loading of toolbox /Volumes/YUSUF'S HD/spm8/toolbox/HDW/._tbx_cfg_hdw.m failed. Loading of toolbox /Volumes/YUSUF'S HD/spm8/toolbox/SRender/._tbx_cfg_render.m failed. Loading of toolbox /Volumes/YUSUF'S HD/spm8/toolbox/Seg/._tbx_cfg_preproc8.m failed. Loading of toolbox /Volumes/YUSUF'S HD/spm8/toolbox/Shoot/._tbx_cfg_shoot.m failed. ......done When I move the SPM folder to my desktop and set the path to there, I don't get these errors and it is exactly the same folder, can anyone help. Thanks Yusuf
