Error parsing Blast results

[dylancarman561@…]

The following bug report has been submitted:
Platform:        Windows-10-10.0.19043
ChimeraX Version: 1.3 (2021-12-08 23:08:33 UTC)
Description
I downloaded ChimeraX and was watching some tutorials when I was prompted with an error message when I attempted to use the Blast Protein function. 
Below is the run error I am encountering.
BlastProtein failed:

Hi Dylan,

As you were going through your tutorial, I was rolling out an update to our backend which took longer than expected. I apologize for any inconvenience that caused you, please try again today and let me know if it's working for you. I've just tested a BLAST job and it appears to be in working order.

[Zach Pearson]

Root cause was the same as #5998; apache could not write into the directory it was set to use to store the results of jobs. As I noted in that ticket, this has been fixed and should work now.
