problem when executing without aligning images #13

Hi!
I wanted to post a little issue I faced, which is that when I use for the first time the -a option (not to align the images) then the process fails.

I am using aligned images so there is no need to align again.

If, however, I use the option -a even once, then the problem goes away:

Below is an exert from running atrack for the first time on a set of images with the -a option (fails). Then running it without the -a option (ok) and then running it with the -a option (ok).

Thank you in advance,
Petros

Because lines=[] is empty, error turns out when send to pool.map
