Alpha Fold Google Colab Sign In

[b385057@…]

Good evening,

I recently started to use ChimeraX for my protein visualizing research project and when I tried to predict a protein structure based on my own sequence, I accidently logged into Google Colab with my school email which is restricted for Colab so I can’t use it. When I try to sign out of my school account I am redirected by ChimeraX to an error page. I have not been able to sign in with my different email, and therefore cannot utilize the prediction tool of chimera, which is key to my research, and I was hoping if you could help me to sign out and sign back in with the correct email address. The email I used to sign in to Colab that is restricted is benyamin.zilber69@… and the email I would actually like to use is b385057@….

Sorry for the inconvenience,
Benyamin Zilber

I just tried the AlphaFold tool in ChimeraX and ran a prediction and when the warning about the code not coming from Google appears with "Run Anyway" and "Cancel" buttons I pressed Cancel. Then I clicked on my face icon in the upper right corner of the Google Colab AlphaFold window in ChimeraX and clicked "Sign out". I gather from you got this far and then it went to some kind of error page. For me it correctly signs out and lets me sign in to a different account.

So it all works for me with ChimeraX 1.4 tested on a Mac (macOS 12.6).

I recall the ChimeraX web browser panes sometimes giving "Not found" errors in older ChimeraX. Are you using the ChimeraX 1.4 version?

If none of this works, there is a file which keeps your Google sign-in for ChimeraX active. On Mac it is in

~/Library/Caches/UCSF ChimeraX/QtWebEngine/AlphaFold

Deleting that directory should make it forget your Google sign-in.

Thank you for your help. You were partially right, I did need to delete the
local cache file, but turns out I also had Chimera saved in my roaming, so
I had to delete it in both of those places for it to finally forget me.
Again, thank you for your help.

Glad you got it working.
