Error when merging 2 channels

Hi,

I am trying to use BiofilmQ to analyze a confocal Z-stack with 2 fluorescence channels & compare relative biomass. After successful “cubed” segmentation of both channels, I click on “Post-processing --> Merge Channels … --> 1 to 2 --> Perform task” but then I get the following error message(s) [see below]. Any idea on how to solve this?

Cheers
Elisa

Hello Elisa,

thank you so much for alerting us to this error. BiofilmQ is still in its beta version, so any feedback - especially concerning bugs - is incredibly valuable to us.

We fixed the issue and updated our BiofilmQ versions on the website, so you can now download and install a corrected version. I apologize for the inconvenience and the delay in answering to your post.

If you have any other questions or feedback, I´d be happy to hear about it :smiley:

Best,

Hannah
