[edit] RNAseq

* Useful RNA-seq tutorial pages by Jeremy on Galaxy Pages 
* Tophat
  * formula for "mean inner pair distance":
    * !HudsonAlpha 50bp paired ends: 150, normally. 
* Cufflinks
  * To run cufflinks so that transcripts have usable gene names, use one of the patched GTF files in the Shared Data Library "Patched GTF annotation files for Cufflinks" (created by David C & Curtis H). These have the gene symbol/name patched into the gene_id attribute. 
  * NOTE: if you supply a GTF of existing annotation, it will NOT discover novel splice variants, as galaxy uses the -G flag instead of the -g flag (Cufflinks docs)
  * BUG: Runs but produces all 0 ouput if there are "_" (underscores) in the chromosome names (TreeShrew problem - names were GeneScaffold_####!) - still under investigation - may alternately have been caused by sheer number of chromosomes (scaffolds)

[edit] sam_chr_coverage

Compute read coverage by chromosome (By John ozborn@uab.edu) First argument is a SAM file to process Second argument is the reference genome fasta used to create that SAM alignment (Available Genome Abbreves: hg19, mm9, mycoplasma_fh, mycoplasma_m129, vaccinia_wr_genome)

[edit] q_gunzip

Take a list of files (or directories) and qsub a gunzip job for every .gz file listed or findable in the directory tree. Author: Curtis curtish@uab.edu Note: Symbolic links are NOT followed!! dir [additional file

[edit] patch_GTF_with_gene_map.pl

[not yet available] Update the gene_id field in the GTF to contain the gene name, for use with Cufflinks, so it reports in terms of gene names. Gene names can be pulled from an text map file, pulled from the gene_name attribute w/in the GTF itself. Author: Curtis curtish@uab.edu {{{ /share/apps/galaxy/galaxy-tools/bin/patch_gtf_gene_id -src mm9_head10.gtf [-map UCSC_mm9_fake.txt] -prog 3 }}}
