Hi All, We are trying to run a dual regression on resting state ICA data using this command: dual_regression groupmelodic.ica/melodic_IC.nii.gz 1 NewModel_Jul17.mat NewModel_Jul17.con 5000 dualreg_output `cat ICA_List.txt` It seems to work fine and gives us stage 1 and stage 2 results however it can't output stage 3 files. The only error that we can see is in drB and states that it cannot open volume mask ALL for reading even though the file has been created. Here is a link to the scripts and logs that the analysis has created so you can have a look: https://drive.google.com/open?id=1-2XlnM7h4OO2nNM66UX6Iq9A8mFH_nrR Thank you in advance!
