Error configuring multiclamp 700B

[Antonin Blot]

Hi,

I'm trying to install acq4 with a multiclamp 700B and I have a new error: `NameError: UNITS_VOLTS_PER_VOLT`.  As far as I can tell the wmlib object is created by MultiClampTelegraph.py without error and has all the basic properties (like PeekMessageA for instance) but none of the methods starting by MCTG or the units conversion factor. Since I add some pyparser issue at first, I tried to delete my MultiClampBroadcastMsg.hpp.cache and restart but that didn't solve the problem.

  I installed anaconda in 32 bits, so that shouldn't be the issue. Do I have to pay attention to the exact version of multiclamp commander that I have installed on the computer?

Thanks!

Hi Antonin, I just saw this error a couple of days ago myself. Will let you know when I have a solution.

This is now fixed in the most recent develop commit. If you are using a distant branch, it should be easy to cherry-pick this one:

Dear Luke, 

I was trying to access our new multipclamp 700B amplifier with ACQ4 this afternoon and got the same error as reported by Antonin  (Sep 11, 2018, 3:25:41 PM). The fix https://github.com/acq4/acq4/commit/ba7cd340d9d0282640adb501d3788f8c0837e4c4 didn't do the job for me. Or am I missing something in your instructions? 

Any chance I can fix that in the python2 version of ACQ4? I tested the current develop branch (using python 3) and the 700B is working with it. However, I don't have the time and resources to port our entire ACQ4 ecosystem to python3 right now. 

I would appreciate if you can get a quick hint. Thanks in advance. 

Cheers,

Michael

Hi Michael,

What if you just take the most current version of the multipatch device + driver code and backport it to python 2? I would guess this is relatively easy.

Luke

Hi Luke, 

Thank you for your prompt reply. I will try this today.

Hi Luke, 

I just ported the current multipatch device+driver code, backported it into our current python2 environment and still get the same error :
