[Chimera-users] Help using Chimera with SFLD - I cannot 'view in chimera'

[Elaine Meng]

I’ve also reproduced the crashing behavior, but I’m pretty sure it is due to the SFLD output problem rather than Chimera per se.

For the developers’ benefit:  I got the crash by viewing an alignment in the SFLD viewer, and in the resulting page with the alignment, clicking the small Chimera icon to open MSF format in Chimera.  If I instead click the text next to it “Open raw MSA file”  the browser then shows “Internal Server Error” suggesting it is again a failure to serve up the proper data.

However, downloading data as fasta (unaligned, so not what you wanted) and downloading networks seems to work OK.

The URL for the sto file gives an error in the browser, e.g. [Errno 13] Permission denied: u'/tmp/sfld/alignment_WSLmTdwA.sto’  and the local temp-data file given in the Chimera error message does not exist, as far as I can tell.

I cannot open enzyme active sites in Chimera, or HMM alignments. I have updated by chimera. I am running Mac OS X 10.10.5, and firefox 56.0.2
