Indexing with STAR

Indexing with STAR 0 Hello, I am working with RNA seq data and creating an index of reference genome Gossypium hirsutum by using STAR. STAR asks GTF annotation format while my file is GFF3. According to literature, in order to run GFF file I need to remove –sjdbOverhang 50 and…

How to download the Homo_sapiens.GRCh38.100.gtf and Homo_sapiens.GRCh38.dna.primary_assembly.fa files for my analysis?

How to download the Homo_sapiens.GRCh38.100.gtf and Homo_sapiens.GRCh38.dna.primary_assembly.fa files for my analysis? 0 I am trying to perform STAR alignment and I need the reference files for indexing. I would like to know how to download the Homo_sapiens.GRCh38.100.gtf and Homo_sapiens.GRCh38.dna.primary_assembly.fa files so that I can use my following code for indexing…

STAR Genome Indexing

STAR Genome Indexing 0 One of the arguments that STAR –genomeGenerate takes in is sjdbOverhang which the manual says “specifies the length of the genomic sequence around the annotated junction to be used in constructing the splice junctions database” and that it should be equal to read length – 1….

STAR rna-seq for bacterial genomes

Hi, I’m willing to use STAR for bacterial genomes. I wanted to ask if this is strongly unadvised or if there is a way to manage the main challenges of mapping reads to prokaryotes. (I know there are specific tools for this purpose, i.e. EdgePro, but I’m a beginner in…
