loadfile.m should open both types of MAT files (created by this repo, and previous tools).

Is your feature request related to a problem? Please describe.
On the surface, there is no way to know what type of MAT file one is opening (whether it was converted through the old system, or through this one. The difference is mainly in the structure of the event markers.

Describe the solution you'd like
loadfile.m should check the file, and open it either way. It can check if event_markers is a table or a struct, and if struct, parse to table. If not, pass.
