Transferring arrow files between projects

[boconnell89]

Is there a way to create an ArchRProject with ArrowFiles created for another project (with the same reference genome, etc)? I'm trying to avoid having to process some very large files from different sources, that I wish to load into an ArchRProject to compare. Each of these has takes about a day to create an ArrowFile, so I'd like to avoid that if possible.

Arrow files can be copied and used in multiple projects. Problems will arise if multiple projects share the same copy of an arrow file though. So we typically create the base Arrow file and then create an ArchRProject using copyArrows = TRUE to prevent the project from editing the original arrow file copy.
