Hi,
I am running into trouble with motion correction on my Mac and freesurfer 4.5. Originally I ran preproc-sess and got an error from mc-sess in the part (i think) that runs the mcextreg. I ran mc-sess and the same error happened (I have copy pasted the log bellow). It seems like the matlab program that runs mcparams2extreg cannot read the fmc.mcdat file. when I did textread('fmc.mcdat') in matlab, I could open the file and it looked perfectly fine to me with the correct number of TR's. Any idea where the problem might be?

Hi Maryam, I don't know what is going on. Does 006/mcparams2extreg.log have anymore information? Can you run
cd 110419_xu_PDM1_02_PDM/bold mcparams2extreg -mcfile 006/fmc.mcdat -northog 6 -extreg 006/mcextreg
