phasing and Allele Specific Expression from RNA-seq

Performs haplotype phasing using read alignments in BAM format from both DNA and RNA based assays, and provides measures of haplotypic expression for RNA based assays.

Developed by Stephane E. Castel in the Lappalainen Lab at the New York Genome Center and Columbia University Department of Systems Biology.

Please see our paper in Nature Communications for details and benchmarking of the method.

A bug was introduced in version 0.9.8 (12/16/16) and fixed in version (06/21/17) that caused problems with haplotypic counts when using the --haplo_count_blacklist argument. This bug affects the haplotypic counts generated (haplotypic_counts.txt), and any downstream analyses of those counts, including generating gene level haplotypic expression with phaser_gene_ae. If the --haplo_count_blacklist argument was not specified, then the results were not affected. In addition, a new "hg19_haplo_count_blacklist.bed.gz" file has been uploaded, which addresses problems related to this issue. If you used the --haplo_count_blacklist argument with a version of phASER between 0.9.8 and you must re-run your analyses with version
