error while extracting raw data

Hi All,

I am trying to extract the sources for V1 (left hemisphere) from the raw
data of one subject using mne_compute_raw_inverse. However, I am getting
the following error:

Source index out of range 157452 (range 0..157394).

When I load this subject's averaged evoked data in mne_analyze, I see
plenty of activation inside the boundries of the V1 label that I am using.
I haven't had any trouble extracting sources from rh V1.

Is anyone familiar with this source index error?

Thanks for your help,

Matt

Hi Matt,

Are you sure both the label file in question and the inverse operator belong to this subject? The error means that the label file contains a vertex number which is larger than the number of vertices in the (left hemisphere) cortical surface contained in the inverse operator file.
