Dear Jorge and FreeSurfers,

I have just been running lme_mass_fit_vw for 6 hours, and I have seen many thousands of messages like the following:

"Location 337813: Convergence at iteration 4. Initial and final likelihoods: 607.8828, 611.1052.
Location 337812: Convergence at iteration 4. Initial and final likelihoods: 603.0934, 604.4513."

etc....

There was the very occasional message saying the algorithm did not converge at some location, a message I saw only 2 or three times (although I wasn't looking at the matlab window for 6 hours straight, thankfully).
I thought, so far, so good.

I came in to work this morning however, and found that it had finished, with the following ugly message waiting for me:

"Algorithm did not converge at 99.9997 percent of the total number of locations.
Total elapsed time is 357.4368 minutes."

I have two questions please.

1) Should I believe this message, even though it seems to contradict what has been printed to the screen while lme_mass_fit_vw was running?

2) If it really is a problem, what would you recommend I do to remedy it? Set the convergence epsilon to 10^5?

Any help is much appreciated.

Best wishes,

Seán
