Problem with Fieldtrip conversion

[Vladimir Litvak]

Hi Michael,

I'm glad to hear that you started looking at SPM :-)  This is more of
an SPM than a Fieldtrip question so perhaps the discussion should move
to the SPM mailing list. Just from looking at the error message the
problem doesn't look familiar. Could you send me your file with the
struct (via yousendit.com if it's big) and I'll try to reproduce it?

Best,

Vladimir
