Written for analysis of Hematodinium differential gene expression
This script produces the CSV needed for GO-MWU, which is a 2-column table of accession IDs and unadjusted p-values. A header line is required, although the contents are irrelevant.
GO-MWU also requires another input file which we already created - a tab-delimited 2-column table of accession IDs and GO terms with no header and only 1 line per gene
This script utilizes a function built for this analysis by me - geneids_pvals(). It is defined in hematodinium_analysis_functions.R
input_file: DESeq2 output file containing transcript IDs and unadjusted p-values
blast_file: path that leads to transcript ID/accession ID table. Optimally, use an annotated BLASTx table of the same transcriptome used to create the kallisto index
output_file: path to the output file - a 2-column CSV of accession IDs and unadjusted p-values with a header line. This should be written to the same directory that you will run GO-MWU in.
