Export Label Source as Scalar

[cmhulbert]

Currently possible via paintera-conversion helper, but should be possible from the UI.

[SteveNeustadter]

I am attempting to use paintera conversion helper via anaconda in the mac terminal, but am met with java related error messages. What workflow should I follow to import the N5 Data into a scalar N5 format to Fiji ImageJ so I can finalize a conversion to tiff image.

I should note that I am on an M2 Mac

libblosc is missing, it looks like your are on Linux, so this should be easy, e.g.

sudo apt install libblosc1

They mentioned they are on a M2 Mac:

You can use conda or homebrew:

https://anaconda.org/conda-forge/blosc

conda install -c conda-forge blosc

https://formulae.brew.sh/formula/c-blosc

brew install c-blosc

Also see notes from the JBlosx package itself:
https://github.com/Blosc/JBlosc

Depending on the circumstances you may need to set the Java configuration option jna.library.path
