Hi Nils
Just wondering can SRMA be used for rescuing orphaned reads. So we have a dataset of variable insert library as we are sequencing the 5' and 3' end of transcripts. As a result the distance between the mates( <--- --->) is dependent on the length of transcript. To map the reads initially I am first using Mosaik which i belv does a better job with variable insert mate pair data.
After mapping we still see 40% orphaned reads where one read maps and the other doesn't. I am wondering if SRMA can rescue these reads.
Thanks!

We have also parallelized the GATK implementation of LR if you are interested. I am not sure which is better at realigning. I do remember comparing SRMA and GATK LR and there are differences but it was not clear to me if one was consistently better than the other. I suspect that Nils would be a better source for info on that.

Tried several bams with 0.1.16 but all I got was this:

I have been interested in this tool for some time but never got it working:
Input is a sorted bam.
java -Xmx16g -jar srma-0.1.15.jar I=491_full_s.bam O=srma_491.bam R=../NC_002516.fna

The fasta index file looks like this:

Cheers for any help.

There are thousands of lines of these error messages. If I copy the stderr output, it will be too many lines. You can replicate my problem by downloading the pair-ended reads from
ftp://ftp.1000genomes.ebi.ac.uk/vol1...sequence_read/
and then align them using bwa. I got the same bug with SRR098401_*.filt.fastq.gz and SRR035330_*.filt.fastq.gz

The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...-

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-
