<div dir="ltr">Hi Tom,<div><br></div><div> Thank you for your quick reply. Your solution worked to get "foreach" to work and I have notes below if others in the future run into my problem. I was able to solve the issue with a bash script that creates command run files on the fly but it's pretty messy so if you have another way to do this it'd be nice to have things a bit cleaner. Below is my solution/follow-up question, a clarification to the $file1 question you asked and some notes about updating. Major apologies if I repeat myself or grammatical errors, as I wrote this email I came up with several ideas on how to make things work and had to edit the post multiple times each time I tried something new.</div><div><br></div><div>Follow up question:</div><div> With your help I got this to work by typing these commands into the terminal directly:</div><div>$:chimerax --nogui</div><div>(waited to load chimerax)</div><div>$:open chimera-data-processing.cxc foreach S_0001_*-4-all-chain-A.pdb</div><div><br></div><div> Is there a way to run the command script with foreach while opening chimerax? for example:</div><div>$:chimerax --nogui chimera-data-processing.cxc foreach S_0001_*-4-all-chain-A.pdb</div><div> </div><div> If I run this it give me a bunch of python errors and errors related to $file.

I have 2 input files. a model with no metals and a template with models I need to align onto.</div><div><br></div><div>Updating issues:</div><div> </div><div> I forgot to mention that I tried updating chimerax-daily with this command</div><div><br></div><div>sudo /usr/bin/chimerax-daily -m pip install --upgrade pip<br></div><div><br></div><div> which gave a success code. But when I checked the version via chimerax-daily --version I get this version.</div><div><br></div><div>UCSF ChimeraX version: 0.93 (2020-03-24)<br></div><div><br></div><div> Is there a way to update to the newest version without reinstalling? I found toolshed update documentation but this appears to be for packages not the entire build. As you can see it is not them most updated version. I downloaded bother chimerax and chimerax-daily again. chimerax installed and used foreach with no errors. However, chimerax-daily will not install unless I do a complete uninstall so I think I'll go forward with chimerax.</div><div><br></div><div> Another thing I noticed, while attempting ranges with chimerax-daily it only took single digit ranges. For example </div><div>S_0001-[1-10]-chain-A.pdb if only took pdbs with "1" in place of the range. if the range is 1-9 then it takes all files. If the range is 01-19 (trying to match number of digits) if only takes models 1 and 9. I get what it is doing here but I don't know the fix or if I'm doing it right. I'm just using a range for now to test 9 files instead of the full 1000. I'll replace the numbering with a '*' so it'll get them all. I won't have an issues going forward but thought this was significant for others in the future if I had typed it wrong.</div><div><br></div><div>Thank you again for your time and help,</div><div><br></div><div>Ryan</div><div><br></div><div> </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, May 5, 2022 at 12:01 AM Tom Goddard <<a href="mailto:goddard@sonic.net">goddard@sonic.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="overflow-wrap: break-word;">Hi Ryan,<div><br></div><div> The "foreach" option you tried is exactly intended for this use. The error message "Missing filename suffix foreach" suggests you are using an old version of ChimeraX (older than ChimeraX 1.3) that does not have the "foreach" option so it thinks that "foreach" is the name of a file. Your script only saves one file so I don't understand what you mean by saving two files $file1 and $file2. You would just use "save $file-sf-aligned.pdb ..." to save the aligned file.</div><div><br></div><div><span style="white-space:pre-wrap"> </span>Tom</div><div><br><div><br><blockquote type="cite"><div>On May 4, 2022, at 10:41 PM, Ryan Woltz via ChimeraX-users <<a href="mailto:chimerax-users@cgl.ucsf.edu" target="_blank">chimerax-users@cgl.ucsf.edu</a>> wrote:</div><br><div><div dir="ltr">Dear community,<div><br></div><div> I'm sorry if this is a repeated question, I've seen a few posts about taking in a file for the command line and doing some things then exiting.

Now I need to insert the 5 metals into 5 different pockets into all my decoys for a final relax before selecting my top model. I have a template pdb with all the metals in place. For 4 of these metals I have used rosetta align mover to align a decoy onto the template around a single metal binding site, save the pdb, then add on the metal coordinates then repeat for the next binding site. So this method works because the chain is continuous around these metal binding sites. However the final metal binding site is in the center and coordinated by 4 chains coming together and the positioning needs to be very precise. </div><div><br></div><div> Chimera or chimerax solves this very well but I don't know how to put this into a script.
