Usage: velocyto run10x ac: adjust colors, while keeping the vector names armaCor: A slightly faster way of calculating column correlation filter. If you need to merge the reads, I would recommend doing it with another tool before mapping, but keeping the merged cDNA sequence and barcode sequence as separate reads - this way you will be able to use solo 3' options. Note that adding the -e flag to the pip command installs the software in development mode, when a package is installed this way each change to the source immediatelly reflects to changes in the installed library.
