File loading issue

[ynapetrova]

Hello!

Since recently I have been having a problem when trying to load the images from the scanned folder. The plug-in is able to detect the images but not to load them, which then does not allow to continue with spot detection. I am using Chrome as suggested and the plug-in is fully updated, I also tried with Edge but I encounter the same issue. Maybe it is relevant to mention that no error message is appearing, it just says "Loading images. Please wait.." on top, but then nothing happens. I am using a Windows 10 device.
Here is also a console log:

Hello,

I can reproduce this error. It seems to be caused by the fact that you use a number (561) as the name of the channel, use a (alpha)numeric name (such as fish561) solves the problem for me.

maybe you can give this a try.

I will dig a bit deeper and update the plugin to solve this problem.

Thank you a lot! This indeed also worked for me.

@Henley13 this issues seems to be caused by a known problem in Pandas (pandas-dev/pandas#24939), where underscore are added to column names when using the function df.to_dict('records'), as used here

This was fixed in version 0.24.2, so would it be possible to change the requirement to

pandas >= 0.24.2

good to know that this works now, for the moment, the workaround is using identifiers that also contain letters. with a future upgrade, numbers-only identifiers should work as well.

For the next released version of big-fish yes! Do you have a workaround for now or do you need an urgent patch?

[muellerflorian]

there is not absolute urgency. the workaround is using a letter in the naming of the channel. so that's doable.

so it can wait for the next release of big-fish
