Alignment workflow

The alignment workflow starts with the fastq data and performs QC, aligns reads to the genome, post-alignment QC, creates TDF file for visualization and read count of transcripts.

Differential expression workflow

This workflow uses the expression count data from the alignment workflow and computes the differential expression between all transcripts.


Group_1_vs_Group_2.norm.gct
Normalized expression count data for all samples in GCT format. This file may be use for GSEA or similar programs.
Group_1_vs_Group_2.cls
Class information in CLS format.
Group_1_vs_Group_2.diffexpr.w_symbols.txt
A table showing the fold change, p-value and multiple hypothesis corrected p-value for all the transcripts
Group_1_vs_Group_2.min_count_10.pval_0.05.up.txt
Transcripts where expression goes up, mean expression count >= 10 and p-value < 0.05
Group_1_vs_Group_2.min_count_10.pval_0.05.down.txt
Transcripts where expression goes down, mean expression count >= 10 and p-value < 0.05
Group_1_vs_Group_2.min_count_10.pval_0.05.all_ids.txt
Id of all transcripts where expression is going either up or down, while mean expression count >= 10 and p-value < 0.05
Group_1_vs_Group_2.min_count_10.pval_0.05.all_ids.png
Heatmap showing the transcripts going up or down
