[Mne_analysis] No Isotrak data found in (raw .fif file)

[Krieger, Donald N.]

Hi Steve,

You might just look at the tags in the file using the Elekta tool: show_fiff .  There's probably an mne or mne matlab toolbox tool which enables this too.

Subject: [Mne_analysis] No Isotrak data found in (raw .fif file)

Hello MNEers,

While doing MRI-MEG co-registration, for one particular subject when I open mne_analyze and try to Load Digitizer Data from the raw .fif file, I get this error:

No Isotrak data found in (the name of the .fif file)

I haven't gotten this error for any of my other subjects, and I processed them all the same way using a batch. Just now I tried re-doing some of the processing for this subject (epoching, artifact rejection, and filtering had already been done in CTF, but I redid the import to .fif, averaging, and noise covariance matrix), and still got the same problem.

Does anyone have any idea what might be causing this error and how to fix it?

Best,
Steve Politzer-Ahles
