Hi thank you for posting this, a few others were asking about the memory issues with merging the files.
This step is just merging the tow/more data frames into one data frame and is using the basic R merge
function. This function in R is known to be very RAM/memory intensive and that's why this happens. But you can use any other method to put all your files together, like using bash join command or python. But soon in a new version of iCellR I will probably use something other than the merge
function to prevent this from happening for the users who run their data locally.

This is fixed. Use version 1.5.0.

Hello,
I am trying to test out iCellR, however, I can't seem to get through the data aggregation step. As soon as I load one 10x dataset, there will be a >80% system memory usage and the aggregation step will fail as it cannot allocate a vector of 274kb. This is on a system with 8gb ram with nothing else running. Using a system with 16gb ram seems to work fine, but memory usage was still >80%. I am wondering if there is a way to use iCellR with less than 16gb ram?
Thanks!
