Hello, while trying to load either docker/singularity image I encountered similair error message (for full information see below).
The main issue seem to be related to following problem:
Error in strsplit(opt[["preproc"]], ","): This error suggests a problem with the strsplit function, which is typically used to split a string into substrings. The error "non-character argument" implies that opt[["preproc"]] is not a string. This could be due to opt[["preproc"]] being NULL or of a different data type than expected.
Thank you for any help in advance.
