| I have been trying to run spm_mask.m. but get the following error | messages. | | ??? Error while evaluating uicontrol Callback. | ??? Error using ==> run | Undefined function or variable 'p'. | | ??? Error in ==> /export/home1/seanc/spm99/spm.m | On line 1180 ==> evalin('base',CBs{v-1}) | | Can anyone help. This is my fault because the released version of the function was not tested. There is a fix for the reported problem at: ftp://ftp.fil.ion.ucl.ac.uk/spm/spm99_updates/spm_mask.m Best regards, -John
