Sinto: single-cell analysis tools

Sinto is a toolkit for processing aligned single-cell data. Sinto includes functions to:

• Subset reads from a BAM file by cell barcode

• Create a scATAC-seq fragments file from a BAM file

• Add read tags to a BAM file according to cell barcode information

• Add read groups based on read tags

• Copy or move read tags to another read tag

• Copy cell barcodes to/from read names or read tags

• Add cell barcodes to FASTQ read names

Version 0.8

0.8.1

• Fixed bug in nametotag when cell barcode in the middle of the read name (https://github.com/timoast/sinto/issues/46)

• Remove need for samtools in path (https://github.com/timoast/sinto/issues/41)

• Added --outdir parameter to filterbarcodes

• Added --sam parameter to filterbarcodes

• Fixed bug in filterbarcodes and addtags causing read groups to be modified (https://github.com/timoast/sinto/issues/17)

0.8.0

• Added tagtoname and nametotag commands to copy cell barcodes to/from read tags or read names

Version 0.7

0.7.6

• Added --collapse_within parameter to fragments function to enable only collapsing PCR duplicates if the cell barcode is the same (https://github.com/timoast/sinto/issues/36)

• Added tests for fragments function and associated small test dataset

0.7.5

• Added --shift_plus and --shift_minus parameters to configure Tn5 shift applied in fragments function (https://github.com/timoast/sinto/issues/33)

0.7.4

• Fixed bug causing some fragments at the end of contigs to be dropped (https://github.com/timoast/sinto/issues/31)

0.7.3

• Fixed error in soft clipping for fragments function (https://github.com/timoast/sinto/issues/29)

0.7.2

• Added min_distance parameter to fragments

• Fixed bug in soft clipping for fragments function

0.7.1

• Code style update for tagtotag and tagtorg

0.7.0

• New tagtotag function to copy or move read tags

Version 0.6

0.6.1

• Bug fixes for barcode function

• Allow running barcode on unzipped FASTQ files

0.6.0

• New barcode function to add cell barcodes to read names in FASTQ file

Version 0.5

0.5.1

• Fix bug in utils.read_cell_barcode_file when same cell appears on multiple lines

0.5.0

• Add tagtorg command to add read groups to BAM according to cell barcode.

Version 0.4

0.4.3

• Throw error if file is not present for filterbarcodes and addtags
