Hi Pablo,
I would start with a different approach.
What if you would try/catch a "am I on WSL" test in Scipion like 'wsl.exe --status' or 'wsl.exe --list' and if yes put the ScipionUserData folder instead of /home/user/ScipionUserData to /mnt/c/Users/user/ScipionUserData
Not sure how safe is this but I've seen in my WSL env I got "WSL_DISTRO_NAME" I'm using it existence to "mark" Scipion is running on WSL (how weak is this.... we'll see).
or if not enough space on c: the user could modify scipion.conf to SCIPION_USER_DATA = /mnt/d/ScipionUserData /mnt/d could then also be not only an internal drive, but an external harddisk. Maybe due space reasons the CryoEM movies are already there for the import and motion correction steps.
Then you must only replace /mnt/c to C: and the / to \ (or \) in your call of Chimerax.exe from WSL2.
In addition I think Windows user would appreciate it to browse the Scipion project via the Windows filebrowser and look at files e.g. in the extra folder by double-clicking on them. Also backing up the project is easier from Windows than using commandline tools like rsync, scp, ...
umm! Nice idea... not sure if we can make a "FileHandler" to launch windows filebrowser, but will make a note.
Cheers, Wolfgang

Hi Pablo, Thanks for the clarification. As I said in my email, one of our developers (Zach) claims ChimeraX can be installed on WSL. I didn't realize there is a WSL2, but Zach probably tested with that since WSL2 came out in 2019. The second point is Zach said performance of ChimeraX on WSL was significantly worse, so that is probably not desirable. As for Scipion launching ChimeraX to open a map file, it seems like Scipion of course has to know whether it is launching a WSL ChimeraX that uses a file path /home/pablo/mymap.mrc or Windows ChimeraX which requires a path like \wsl.localhost\Ubuntu-22.04\home\pconesa\mymap.mrc. I don't think ChimeraX can help automatically correct paths that were specified for a different operating system. Scipion has to give a legal path for the ChimeraX it is invoking. A Windows ChimeraX would have no idea that Scipion on WSL2 launched it.
So I still have not heard of anything that ChimeraX developers could or should do to help WSL2 users, except maybe to advise them that running ChimeraX on WSL2 will give poorer performance than running on Windows natively.

We Integrate many cryo-em (not only cryoem) software and ChimeraX is among them. We tipically work and develop in native Linux OS. Recently users, are using WLS2 to install Scipion and companions and in this case ChimeraX wasn't an option to be installed in WSL2. So we though, "Ok, let's use windows native chimeraX from WSL2". And here is the "stupid problem": We in scipion know the location of many cryoem/pdb files form the "WSL2 perspactive". e.g.: */home/pablo/*mymap.mrc. Now, ChimeraX as a command is launchable from Scipion as long as we know the path (something that can be configured in Scipion). e.g.: */mnt/c/*Program\ Files/ChimeraX/bin Note that there are here 2 perpectives for the paths: WSL2 and Windows. So, when scipion launches ChimeraX (in the simplest way, we also create more complex cxc files) it can do something like: */mnt/c/*Program\ Files/ChimeraX/bin/ChimeraX */home/pablo/*mymap.mrc These are valid paths from WSL2 perspective, but */home/pablo/*mymap.mrc is NOT valid from Windows perspective. When ChimeraX is launched (as a windows app) it does not recognize */home/pablo/*mymap.mrc as a valid path, since it "technically does not exist". It is actually: *\\wsl.localhost\Ubuntu-22.04*\home\pconesa\mymap.mrc There is a command on WLS2: wslpath wslpath: Invalid argument Usage: -a force result to absolute path format -u translate from a Windows path to a WSL path (default) -w translate from a WSL path to a Windows path -m translate from a WSL path to a Windows path, with '/' instead of '\' EX: wslpath 'c:\users' This might help us to "translate our path to the right windows one" (this would be on our side). But when looking into this issue we though that maybe you "ChimeraX" would like to be aware o this error and maybe ( this is a wild guess) it is a low hanging fruit for you to tolerate this paths.. .or maybe not! I do not know and this is why Dmitry was asking. Note that this is not just a fix for Scipion (we probably can correct this on our side) but a "feature" that will facilitate any*ChimeraX usage from WSL2* (not being ChimeraX on WSL2 installed but on windows).

Also Zach suggested that ChimeraX run under Windows could read and write the data files on the Windows System for Linux (WSL) virtual machine file system. So could you explain what your use case is? We recommend not using ChimeraX on virtual machines because performance may be poor and problems often arise getting hardware accelerated graphics to work.
