[Chimera-users] problems with multifit in chimera

[Nimit Jain]

Hello

I have recently been encountering problems with MultiFit within Chimera 
on both Ubuntu and Windows 10 (trace from reply log below--I get the 
same error on both operating systems). Even fitting with datasets that 
was working earlier in the year (~August-September) is not working 
anymore. My guess is that some changes have happened on the server that 
hosts Multifit. Could someone please try and reproduce the bug and let 
me know how I should troubleshoot this? I am trying to fit a single 
protein structure to an EM map and as I said, this was working earlier 
this year.

I also tried downloading IMP on my Windows machine and using MultiFit 
from in there. This was running into some separate issues which I will 
not go into here since they are not directly related to Chimera.

Thanks and best
Nimit
