comment:2 by Eric Pettersen, 3 weeks ago

Hi Daniel,

Thanks for reporting this problem. There are some odd things in your ticket. For one thing, "seqcrow" 1.9.7 is listed in the installed packages, and 1.9.7 is the current version but as far as I know it should be listed as "SEQCROW", not lower case. If SEQCROW is properly installed, you should be able to open FCHK files (and .out files).
Perhaps you could run the command "toolshed list" and see if SEQCROW/seqcrow is listed among the installed bundles. In either case try reinstalling SEQCROW by doing "toolshed uninstall SEQCROW" (or "... seqcrow" if that's what "toolshed list" showed), then do "toolshed install SEQCROW". Then see if you can open FCHK files (you might have to restart ChimeraX first).

I tried installing the current version of SEQCROW into ChimeraX 1.6.1 (the version you're using) and the install didn't really work. You may have to update to a current version of ChimeraX.

comment:5 by Tony Schaefer, 3 weeks ago 

Eric is correct, it should install properly on a newer version of ChimeraX.
There was an issue installing/updating seqcrow with some of the older
versions of ChimeraX. I forget the exact problem, but it would sometimes
download the bundle and then refuse to load it, and it wouldn't let you
reinstall because it was "installed", but it also wouldn't let you
uninstall because it wasn't loaded. It looks like for the upcoming version
of seqcrow, I've already set it to require at least ChimeraX 1.7. I'd
recommend getting the latest version, though.

Best,

Tony

Thank you all for your help with this. I have just reinstalled the newer
version of ChimeraX and it is all working perfectly now.
