Leginon

We have a XF416 as well. Nice camera. I did not get it to work properly with the new CAMC4, though. Had some trouble with the new calls when I need to reach it through a remote computer like the case Leginon is. A work around is to use EMMENU scripting. See

Tivips_f416_electron_diffraction_recording

For single image acquisition, you won't need to set up recorder, just Leginon view port and tvips.cfg

I don't know if you have XF416E_GPU or XF416. I only produced the subclass for the GPU version but did not coded any function specific to the GPU part, yet.

Hi Anchi,

Sorry, moving at a glacial rate troubleshooting this due to stacks of teaching...

I am now getting a difficult-to-decipher error when I test the camera using pyscope. I note that we actually have TVIPS' EMMENU5 installed, which I'm concerned may be the issue?

Did I mess something up...?

thanks for your continued pointers...

Looks like some compiler problem. I will have to ask TVIPS about EMMENU5.

Our EMMENU is 5.2.12. What is yours ?

Did you install as 64-bit version of python ? What is comtypes version ? It might be a comtypes problem.

Hi Anchi,

Thanks for looking into this.

I installed comtypes from: https://emg.nysbc.org/projects/leginon/files/comtypes-0.6.2.win32.exe

And python from https://emg.nysbc.org/attachments/download/2063/python-2.7.3.msi

Morgan

EMMENU exact version ?

The error message indicates "field bstrImgFolder offset (32/64)
warnings". I think you will need to install 64-bit version python.

Uninstall your 32-bit packages and python Using Windows Uninstall tools, and then delete anything in C:\Python27. It should give you a clean start to do the 64-bit installation.

I had success installing python 2.7.16 and then install comtypes 1.1.7 through pip installation. I added the 2.7.18.amd64.msi In the File link which should work, too. The rest of supporting packages executable are from our site.
