Hi everybody,After a successful melodic analysis, I tried to do the dual regression.It is very strange that the dual regression did not produce any stage_1 results and just skipped to stage 2, which of course failed.My command goes like this: dual_regression melodic_IC 1 desing.mat design.con 500 grot 'list.txt'. I've check the files to make sure their path is correct. The mask has been properly generated but the stage 1 results are missing.I've run the command several times but it was all the same. I really can't figure out what's the problem.Do you have any suggestions?Best,Ethan
