Problem at Zellkonverter finding conda environment

[Yanst86]

Hello,

I am trying to convert SingleCellExperiment object to Anndata/h5ad using writeH5AD, however I get this error:

library(zellkonverter)
Registered S3 method overwritten by 'zellkonverter':

setZellkonverterVerbose(TRUE)
writeH5AD(Traj_RNA, file = 'D:/Python_coding/File_name.h5ad')

I checked the folder mentioned in the error message and it exists but is empty for some reason, however under the 'basilisk' folder I can see a Miniconda app.
I am using a Windows 10 OS. Re-installing basilisk, basilisk.utils and zellkonverter failed to resolve the issue.
I have other conda environments which are available and I use them with my Python coding, If all else fails, I am willing to use them but I don't know how to set basilisk to use them in R.
Apologies if my question is too elementary, my proficiency in Python and managing python packages using Conda is still not quite good.

Thanks in advance for any help.

Hi @Yanst86

It seems like the environment hasn't been created correctly. Could you please try deleting the cache directory where the environment should be (the path at the end of the error message)? That should trigger the environment to be re-created.

Had this same issue after some software updates and can confirm that it worked after deleting the basilisk cache directory and restarting the R session, i.e. rm -rf ~/.cache/R/basilisk/.
