Helllo:

I used SALIGN to obtain alignment / superposition of peptides. On the SALIGN webpage there is a link for Launch Chimera. When I click this I get a download of a file named "show.chimerax". Then nothing happens. The file contents appear to be directing ChimeraX to the data on the web and are as follows:

<?xml version="1.0"?> <ChimeraPuppet type="std_webdata">

<web_files> <file name="alignment.pir" format="text" loc=" https://modbase.compbio.ucsf.edu/salign/results.cgi/job_225330/str-str_out.ali?passwd=lLzU3A8rBT" /> <file name="model1_fit.pdb" format="text" loc=" https://modbase.compbio.ucsf.edu/salign/results.cgi/job_225330/model1_fit.pdb?passwd=lLzU3A8rBT" /> <file name="model2_fit.pdb" format="text" loc=" https://modbase.compbio.ucsf.edu/salign/results.cgi/job_225330/model2_fit.pdb?passwd=lLzU3A8rBT" /> <file name="model3_fit.pdb" format="text" loc=" https://modbase.compbio.ucsf.edu/salign/results.cgi/job_225330/model3_fit.pdb?passwd=lLzU3A8rBT" /> <file name="model4_fit.pdb" format="text" loc=" https://modbase.compbio.ucsf.edu/salign/results.cgi/job_225330/model4_fit.pdb?passwd=lLzU3A8rBT" /> </web_files> <commands>

<py_cmd>chimera.processNewMolecules(chimera.openModels.list(modelTypes=[chimera.Molecule]))</py_cmd> <py_cmd>import MultAlignViewer</py_cmd> <py_cmd>mols = chimera.openModels.list()</py_cmd> <py_cmd> m=chimera.extension.manager for i in m.instances: if isinstance(i, MultAlignViewer.MAViewer.MAViewer): mav = i </py_cmd> <py_cmd> for m in mols: if not m in mav.associations.keys(): mav.associate([m]) mav.match(mols[0], mols[1:], iterate=True)</py_cmd> </commands> </ChimeraPuppet>

What am I supposed to do with this file. ChimeraX does not have a file extension .ChimeraX hence I do not know how to proceed next. Can anyone help? Thanks in advance.
