In the process of generating expression matrices for [CEABIGR](https://github.com/sr320/ceabigr/tree/main/data) (GitHub repo), and in turn distance matrices for these samples, I realized a couple of things:

1. [DESeq2](https://bioconductor.org/packages/release/bioc/vignettes/DESeq2/inst/doc/DESeq2.html) has a function (`assay()`) that will automatically calculate/produce the distance matrices I want.

2. [`StringTie`](https://ccb.jhu.edu/software/stringtie/) comes with a script (`prepDE.py3`) which will spit out expression matrices formatted for import into [DESeq2](https://bioconductor.org/packages/release/bioc/vignettes/DESeq2/inst/doc/DESeq2.html).

So, this should be easy, right? Of course not. LOL. When trying to run the [`StringTie`](https://ccb.jhu.edu/software/stringtie/) `prepDE.py3` script on the [original output from Stringtie on 20220225](https://robertslab.github.io/sams-notebook/posts/2022/2022-02-25-Transcript-Identification-and-Alignments---C.virginica-RNAseq-with-NCBI-Genome-GCF_002022765.2-Using-Hisat2-and-Stringtie-on-Mox/) (notebook), I encountered a parsing error for the very first GTF file it encountered. Considering the GTF file(s) was/are generated by [`StringTie`](https://ccb.jhu.edu/software/stringtie/), it seemed odd that it wouldn't be able to parse the GTF. Doing some investigating, I came across a number of [issues in the Stringtie GitHub repo](https://github.com/gpertea/stringtie/issues) indicating that using a version of Stringtie (e.g. <`v2.2.0`), with a certain combination of arguments (specifically, the `-e` argument seemed potentially problematic) could create various errors if using that output with an updated version of [`StringTie`](https://ccb.jhu.edu/software/stringtie/). Well, I was doing just that! Was it causing the parsing error I was experiencing? Don't know, but I'd also like to avoid the other downstream errors potentially associated with the output(s) from the older version of Stringtie, so I've decided to re-run the analysis using a the most current version of [`StringTie`](https://ccb.jhu.edu/software/stringtie/).


I used the [trimmed RNAseq reads from 20220224](https://robertslab.github.io/sams-notebook/posts/2022/2022-02-24-Trimming-Additional-20bp-from-C.virginica-Gonad-RNAseq-with-fastp-on-Mox/) (notebook). I also needed to identify alternative transcripts in the [_Crassostrea virginica_ (Eastern oyster)](https://en.wikipedia.org/wiki/Eastern_oyster) gonad RNAseq data we have. I previously used [`HISAT2`](https://daehwankimlab.github.io/hisat2/) to index the NCBI [_Crassostrea virginica_ (Eastern oyster)](https://en.wikipedia.org/wiki/Eastern_oyster) genome and identify exon/splice sites [on 20210720](https://robertslab.github.io/sams-notebook/2021/07/20/Genome-Annotations-Splice-Site-and-Exon-Extractions-for-C.virginica-GCF_002022765.2-Genome-Using-Hisat2-on-Mox/). Then, I used this genome index to run [`StringTie`](https://ccb.jhu.edu/software/stringtie/) on Mox in order to map sequencing reads to the genome/alternative isoforms.

Job was run on Mox.

## Expects FastQ input filenames to match <sample name>_R[12].fastp-trim.20bp-5prime.20220224.fq.gz

## This is an updated run of 20230821-cvir-stringtie-GCF_002022765.2-isoforms. The previous run used an
## outdated version of StringTie, which may have led to some downstream issues.

Since there are a large number of folders/files, the resulting directory structure for all of the [`StringTie`](https://ccb.jhu.edu/software/stringtie/) output is [shown at the end of this post](#directory-tree). Here's a description of all the file types found in each directory:

- `*.ctab`: See [`ballgown` documentation](https://github.com/alyssafrazee/ballgown) for description of these.

- `*.checksums.md5`: MD5 checksums for all files in each directory.

- `*.cov_refs.gtf`: Coverage GTF generate by [`StringTie`](https://ccb.jhu.edu/software/stringtie/) and used to generate final GTF for each sample.

- `*.gtf`: Final GTF file produced by [`StringTie`](https://ccb.jhu.edu/software/stringtie/) for each sample.

- `*_hisat2.err`: Standard error output from [`HISAT2`](https://daehwankimlab.github.io/hisat2/). Contains alignment info.

- `*.sorted.bam`: Sorted BAM alignments file produced by [`HISAT2`](https://daehwankimlab.github.io/hisat2/).

- `*.sorted.bam.bai`: BAM index file.


The [initial alignments from 20210726](https://robertslab.github.io/sams-notebook/posts/2021/2021-07-26-Transcript-Identification-and-Quantification---C.virginia-RNAseq-With-NCBI-Genome-GCF_002022765.2-Using-StringTie-on-Mox/) which accidentally used untrimmed sequencing reads had some truly abysmal alignment rates (males were ~30% and females were around 45%). This round is a _marked_ improvement. The females exhibit alignment rates around what one would expect (> 80%), while the males, even though relatively low (around 57%), it is drasticalliy better than the 30% seen when using the untrimmed reads. Still, the alignment rates are consistently low/lower in males, compared to the females. Not sure of what this means, but exploring some additional avenues to investigate (e.g. possible residual rRNA, possible contamination with other organismal RNA)

Here's a table. The letter `M` or `F` in the sample name column indicates sex.


| Sample | Alignment Rate |
|--------|----------------|
| S12M   | 58.09%         |
| S13M   | 58.44%         |
| S16F   | 81.08%         |
| S19F   | 82.05%         |
| S22F   | 82.16%         |
| S23M   | 57.06%         |
| S29F   | 75.92%         |
| S31M   | 61.12%         |
| S35F   | 81.95%         |
| S36F   | 80.60%         |
| S39F   | 82.52%         |
| S3F    | 82.31%         |
| S41F   | 78.38%         |
| S44F   | 78.70%         |
| S48M   | 57.60%         |
| S50F   | 82.96%         |
| S52F   | 73.20%         |
| S53F   | 81.48%         |
| S54F   | 77.75%         |
| S59M   | 65.81%         |
| S64M   | 71.53%         |
| S6M    | 57.82%         |
| S76F   | 82.82%         |
| S77F   | 84.37%         |
| S7M    | 58.74%         |
| S9M    | 57.95%         |


As hoped/expected, these alignment rates are identical to [the previous run using an old version of Stringtie from 20220225](https://robertslab.github.io/sams-notebook/posts/2022/2022-02-25-Transcript-Identification-and-Alignments---C.virginica-RNAseq-with-NCBI-Genome-GCF_002022765.2-Using-Hisat2-and-Stringtie-on-Mox/) (notebook).

Now, need to send this data back through Ballgown...
