I tried that also on other functions but it seems also exported functions are
invisible to SnowParam workers. That is really odd since it worked just fine
before. For now since we're approaching the deadline for the new Bioc release
we may opt to switch everything to MulticoreParam despite being just a serial
param on Windows. We'll try to figure out what causes this after the new
release, thanks

Hi Giulia,
One of your errors is raised from L1288 in the file "analysis-functions.R"
if (getOption("ISAnalytics.verbose") == TRUE) { ... }
The error message is "argument is of length zero". Usually, this means
something is wrong with the global option. Then I see at L4812 in
"internal-functions.R", you have
p <- BiocParallel::SnowParam(
tasks = length(common_names),
progressbar = getOption("ISAnalytics.verbose"),
exportglobals = FALSE
)
Please keep in mind that if you use SnowParam, the worker is a fresh R
process and independent with your master. Since you have
`exportglobals = FALSE`, the worker has no idea about the option
"ISAnalytics.verbose" in your master process and hence the error.
To fix that, you can set `exportglobals = TRUE` to let the worker
know the option. If you do not want to export the globals, you can
also add the global option "ISAnalytics.verbose" manually at the
beginning of the function in bplapply.
Best,
Jiefei

having issues with BiocParallel on the Windows platform only. In particular,
trying to debug what the issue might be on a local Windows machine, it seems
BiocParallel isn’t able to find internal package functions and fails at several
jobs that did just fine a few versions ago.
