Re: [labscriptsuite] Changing shot output folder

[Tomáš Lamich]

Hi Jasmine,

This looks to me like your "labconfig" file points to the C: drive, while you're trying to read a file from the Z: drive.

I guess you could keep both your connection table and your shots on different drives if you correctly set it up in the "labconfig" file. Look at the [DEFAULT] and [PATH] sections.

Hope this helps,

Tom

Hello all,

We are trying to switch to saving our shots on our server (instead of locally on the computer we use to run labscript). I thought we could just point the shot output folder to the server Z drive, which is mounted on the localhost computer, but we keep getting the error "Couldn't submit job to control server: H5 file not accessible to Control PC" in the runmanager terminal. In the BLACS terminal, we get:

It seems like runmanager can generate the h5 file and save it in the Z drive, but then when it is passed to blacs to run, blacs cannot open the file to run it. Any help would be appreciated.

Best,
