After previously downloading/trimming/QCing S.namaycush SRA liver RNAseq data on 20220706, Steven asked that I run through Hisat2 for splice site identification (GitHub Issue).

To do so, I downloaded the following NCBI files to Mox:

I also reviewd the metadata for BioProject PRJNA316738 and downloaded the metadata for the project:

Metadata website: https://www.ncbi.nlm.nih.gov/Traces/study/?acc=SRP072750&o=acc_s%3Aa
Metadata file (CSV): SraRunTable.txt

Upon reviewing the metadata, it became clear that each SRA run was part of a set of three sequencing runs for each sample (see the “Library Name” column in the SraRunTable.txt). I used this information to concatenate corresponding FastQs and for setting a read group (RG) in the resulting BAM files for the two subspecies (lean and siscowet), as well as indicate non-parasitized and parasitized. Although, each set of three library sets are part of one of four BioSamples:

BioSample	Ecotype
SAMN04590682	Lean parasitized
SAMN04590683	Lean nonparasitized
SAMN04590684	Siscowet parasitized
SAMN04590685	Sicowet nonparasitized

It’s possible I should’ve set up FastQ concatenation and the BAM RG fields using this information, but this can be dealt with downstream, if desired.

Anyway, an overview of the proccess:

Create HISAT2 genome index.
Identify genome exons and splice sites using HISAT2.
Align trimmed, concatenated RNAseq reads (single-end) to genome using HISAT2.
Use StringTie to idenify alternative isoforms and create output files ready for import to Ballgown.

Analysis was run on Mox.
