0.72 Bug unable to save channel data

[austinc-s]

1. Saving the channel data to database does not work on 0.72.
   Steps:

• Make changes to channel intensity and color
• Save to database
• Load new sample
• Load original sample again
• Bug: Loading channel settings from database does not work, all settings back at default

2. Saving the channel data to .csv does not work on 0.72.
   Steps:

• Make changes to channel intensity and color
• Error: 500 Internal Server Error results from trying to save channel data as a .csv

System Info:
Windows 11 build 22000.348
Microsoft Edge (Chromium) 96.0.1054.43
Data is log1p transformed upon import

Ouch. Thanks. We will have a look.

I could reproduce the error under Windows using the latest version 072 using the 163 core dataset. Error appears in both cases: log transformed and raw data.

Server says:

Nhan, probably related to your changes in DataModel line 590 and 591.

when I debug it, it seems the list_channes array has the full name as indices but you want to access it with short names:

causing a key error:
KeyError: 'DNA1'

Thanks Austin for reporting this issue and thanks Robert for info on the error.

There was a discrepancy in the channel names used for saving the data and uploading the data.

We fixed this issue in the latest release (v0.73_gating), please let us know if you still have issues saving the channel data. Thanks!
