vseries failure: list index out of range

[sshakeel@…]

Hi,
I am trying to run vseries on ChimeraX latest dailybuild on Mac OS. It is giving me the following error:
vseries play <help:user/commands/vseries.html#play> #1
Traceback (most recent call last):

The error from your ChimeraX command "vseries play #1" means that model #1 is not a map series. It should give a clearer error message instead of a traceback. When you open a map series it will say in the log that it opened a series. You may have to at to the open command the option "vseries true" to have it recognized as a map series, for example

open myfiles*.mrc vseries true

Made ChimeraX give a user-friendly error message "No volume series specified" if command does not specify a volume series.
