Error when trying to read HEKA .dat file

[LouisonPineau]

Hello,
I'm trying to use the HEKA and NWB APIs to convert some HEKA dat files to NWB but when I try to read a HEKA file using:

from patchview.HekaIO.HekaHelpers import HekaBundleInfo

bundleTester = HekaBundleInfo('U:/.../... .dat')

traceIndex = [0,0,0,0] ## [Group, Series, Sweep, Trace]
bundleTester.getSeriesSamplingRate(traceIndex)

time, stim, stimInfo = bundleTester.getStim(traceIndex)

data = bundleTester.getSingleTraceData(traceIndex)

I get this error:

---------------------------------------------------------------------------

I have pyqt 5.15.11 , pyqtwebengine 5.15.7 and PyQt5_sip 12.17.0 installed in my venv. Do you have an idea where this might come from ?

Thanks in advance !

Hi
This is most likely due to PyQt, pyqtgraph and associated wrappers version incompatibility.
Here are a list of working version:

• pyqt5 5.15.11
• pyqt5-qt5 5.15.2
• pyqt5-sip 12.17.0
• pyqtgraph 0.13.1
• pyqtwebengine 5.15.7
• pyqtwebengine-qt5 5.15.2
• pyside2 5.15.2.1

Hi !
Thanks for your answer, I tried to update and reinstall the packages but I still get the same error.

Did you try uninstall those package first before reinstalling.
Could you make a new virtual environment in your Anaconda following the documentation here (https://patchview.readthedocs.io/en/latest/installation.html#pip-install). I would recommend to use python 3.10.
