Velocyto run10x example It appears that I lack a the "possorted_genome_bam. The genome annotation file is from https://genome. Ran samtools first to get the cellsorted file. sif velocyto run10x -m repeat_msk. And then ran velocyto in the documentation, it says "If the file cellsorted_[ORIGINALBAMNAME] exists, the sorting procedure will be skipped and the file present will be used. I'm using run10x from the command line tool on mouse data. Use these bam files and run velocyto (on any technique) one by one.

The currently available are: run10x, run_smartseq2, run_dropest These subcommands are just wrappers of the main command velocyto run hey , i solved my problem. gtf The velocyto pipeline takes a long time to complete and requires high amounts of resources (include RAM/CPUs). " For example for a gene with 10 exons the exon on the strand - at the 5' most of the reference sequence (that is always given on the + strand) should be exon_number 10 not 1! velocyto run10x -m rheMac10_rmsk.

I am trying to run velocyto to generate loom files needed for scvelo analysis. Now, this works fine if you have a couple of samples, but then it just becomes silly to Velocyto run10x simply produces a folder called velocyto in the sample directory with a single loom file in it, which contains the needed matrices for the analysis. run10x, in particular looks for the input files in the folder structure of the 10x documents and does not allow to set options that do not make sense for the 10X platform. To start, we will be generating loom files (a file format designed for genomics datasets such as single-cell) for every single-cell sample you used in your Seurat analysis.
