Blast results: invalid literal for int() with base 10

[Elaine Meng]

The following bug report has been submitted:
Platform:        macOS-10.15.7-x86_64-i386-64bit
ChimeraX Version: 1.3rc202111090815 (2021-11-09 08:15:14 UTC)
Description
got one traceback trying to run blast, then got another trying to save the session... hence I cannot save and attach a session

Tested in current release candidate

I was in the middle of a long series of steps from the tutorial I'm working on. The shorter way to the Blast traceback is:

open 1t2p
split
blast #1/b

This first traceback is probably the cause of the second traceback when trying to save a session.

[Zach Pearson]

I know exactly why this is happening. One of the worst quirks of Python is that int(1.7) is fine but int(“1.7”) is an error and should be int(float(“1.7”)) I’ll have a fix in soon.

[Zach Pearson]

​This should fix it, thank you!
