Iris Calliope

Added condition to run calc_widefield_ac instead of calc_ac when there is only .roi file, and no .wid file

In case of trace imaging, load and save meta_info to adata there.

Adapted load meta info to be the same as in load_wid_data

added ignore X error of more copies in archive

Small fix on check_pm_sites.m

Added check_pm_sites.m to visualize activity summary in all sites of a proj_meta

Updated a small bug in screen2pos.m
