TVIPS XF416 camera

Hi Anchi,

As first step in upgrading Leginon 3.1 to Leginon 3.5 I'm installing on our T12 with a new TVIPS XF416 camera (which I never configured for Leginon 3.1). I have an error message, but also wondered -- when I clear the error -- which teitz class this camera should use?

I go to register CAMC4.exe (I need to go into the EMMENU directory for this):

cd C:\TVIPS\EMMENU\Bin CAMC4.exe /regserver

Then run updatecom.py:
cd C:\python27\Lib\site-packages\pyscope C:\python27\python.exe updatecom.py

But get an error:
initializing Tietz CCD Camera Error, cannot find typelib for "('CAMC4 1.0 Type Library',)"

I'm afraid I've not used Windows for a couple of decades so waaay out of my depth with troubleshooting (though tried finding out about inspecting the registry, etc,...).

Do you have any thoughts on how to go about troubleshooting?

many thanks,

Morgan

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.

RE: TVIPS XF416 camera - Added by Anchi Cheng almost 3 years ago

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.

RE: TVIPS XF416 camera - Added by Morgan Beeby almost 3 years ago

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

EMMENU exact version ?

RE: TVIPS XF416 camera - Added by Anchi Cheng almost 3 years ago

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.
