Description diploid-and-auto-tetraploid_gene_counts.txt
Data processing Sequencing reads were trimmed for adapter sequences using cutadapt v1.8.1 and read quality was confirmed using fastqc v0.11.9.
Reads were aligned using STAR v2.7.1a with two-pass mapping to a concatenated human-chimpanzee genome (hg38 and pt6).
The number of uniquely-mapped reads (MAPQ = 255) that overlap each gene was counted with featurecounts from the subread v1.6.0 package using a curated annotation (hg38.pt6.gtf). To generate the annotations, GRCh38.94 human exon annotations from Ensembl were mapped from hg38 to pt6 using pslMap. After removing mappings where the number of bases that map is less than half of the query exon size, we retained only exons that uniquely mapped from humans to chimpanzees. We then removed genes for which exons map to opposite DNA strands, different scaffolded chromosomes, or where consecutive exons map more than 800kb apart. We further filtered out exons where more than 10% of reads from diploid or auto-tetraploid lines map to the incorrect species when mapped to the composite genome.
Genome_build: hg38 and pt6
Supplementary_files_format_and_content: Gene counts for each species are represented with the human ensembl ID in the processed files. For allo-tetraploid lines, each sample is represented twice in the associated processed file, once as human allele counts ("Hs" prefix) and once as chimpanzee allele counts ("Pt" prefix).
