all connections are in use error

[pengyu1608]

Hi, I got the following error when running DoubletDecon, could anyone give some suggestion? Thanks.

Combining similar clusters... Creating synthetic doublet profiles... Step 1: Removing possible doublets... Step 2: Re-clustering possible doublets... Step 3: Rescuing cells with unique gene expression... Error in socketConnection("localhost", port = port, server = TRUE, blocking = TRUE, : all connections are in use

Hi pengyu1608,

Apologies for the late response, I've asked the developer in charge of Step 3 to review this error and see what we can figure out. He thinks the error is due to the automatic detection of cores that the function uses, which may cause problems when working on a computational cluster, or in some cases, on a normal computer. I plan to allow the user to set the number of processors they wish to use while keeping the automatic detection as the default. This fix will be pushed in the next update, which will be coming out very soon.

Best, Erica
