<div style="word-wrap:break-word"><div>Hi Ion,</div><div><br></div><div>What operating system are you working on? It looks like windows, and the first error is a path error, where the function is looking at a Linux-style path.</div>
<div><br></div>This is apparently causing trouble. First you get two errors (starting with ERROR, which are a sign that something went wrong in the low level reading routines), which do not cause matlab to 'crash' directly. Later in the code variables are not what they are expected to be (due to the earlier ERRORs) and this causes a matlab crash (in red).<div>
<br></div><div>So far this whole pipeline has been tested only on the linux platform. I don't know whether freesurfer (in particular the matlab functions that FieldTrip relies on to read in the .mgz files) runs without problems on windows. </div>
<div>Perhaps you first need to find out what causes the first error. It could well be that FieldTrip needs to use a platform specific reading routine here.</div><div><br></div><div>BW,</div><div><br></div><div>JM</div><div>
