Answer: A: HLA Typing understanding
... I am not sure at what level you are confused, so forgive me if this is too basic. This is an explainer on how the HLAs are named: http://hla.alleles.org/nomenclature/naming.html Functionally, you only care about the first few digits. HLA-A - this is the gene. There are a bunch of HLA genes. HL ...

DNA Hybridization Melting Temperature Open Source
... Hi, Is there a good open source software for calculating the melting temperature of two DNA sequences? I have been trying the Biopython MeltingTemp module but it relies on tables for the possible mismatches and many of the possible mismatches are not in the tables, so my sequences get kicked out. ...

Answer: A: Statistical test for replicates
... When you sequence small RNA you often get reads that are the degradation products of longer mRNA. These might be what you are seeing. It will be better or worse depending on the protocol. If it is just a size selection there will be a lot of junk. If you are looking for miRNA there is an enzyme that ...

Answer: A: fastq- dump error
... I got this today too and it actually proceeded through to the whole download even though it had the error message. So maybe wait and see if it finishes? You can do an "ls" to see if it's still loading. If it gives you the stats at the end it's good. ...

Answer: A: RSEM build for C. elegans
... I figured it out but I'll leave it here if anyone else runs into this: RSEM expects a ; after the transcript_id. It's not here in this version of the file. This adds the : to the line and seems to fix it: sed -i 's/$/;/' c_elegans.PRJNA13758.WS253.canonical_geneset.fixed.gtf ...

RSEM build for C. elegans
... Hi, Has anyone had luck getting an RSEM build for worm? I am using: rsem-prepare-reference --gtf /Worm/c_elegans.PRJNA13758.WS253.canonical_geneset.gtf \ --polyA-length 25 --polyA /Worm/c_elegans.PRJNA13758.WS253.genomic_softmasked.fa \ /Worm/c_elegans.PRJNA13758.WS253/RSEM/transc ...

Answer: A: quantification RNAseq and normalization
... Hi KML, I think you need to step back for a moment and think about what each measurement is good for. In general, you want to use counts when you are looking at the expression of one gene in multiple conditions and TPM when you are comparing or ranking the expression of different genes. You start ...

Answer: A: How to remove the RIN (RNA integrity number) effect for RNA-seq data?
... You may want to try looking at the supplements for the GTEx papers. They did a lot of work on that. It also depends a lot on the protocol. If it is PolyA selected you will get biases against short genes because you will lose the 5' end. If it is RNA depleted or hybrid capture your bias will be diffe ...

Answer: A: Can I add TPM values of Isoforms of the same gene to get total gene expression?
... If they are calculated correctly (e.g. with RSEM or similar), the quantification should be divided among the isoforms in a mutually exclusive way. So if you have Isoform1 3 TPM - three transcripts Isoform2 1 TPM - one transcript The total gene should have 4 transcripts per million (i.e. 4 inde ...
