Overview
Introduction

This pipeline computes the correlation between significant copy number variation (cnv focal) genes and molecular subtypes.

Summary

Testing the association between copy number variation 21 focal events and 8 molecular subtypes across 87 patients, 22 significant findings detected with P value < 0.05 and Q value < 0.25.

Methods & Data
Input

- Copy number data file = transformed.cor.cli.txt

- Molecular subtype file = MESO-TP.transferedmergedcluster.txt

- Number of patients = 87

- Number of significantly focal cnvs = 21

- Number of molecular subtypes = 8

- Exclude genes that fewer than K tumors have alterations, K = 3

Fisher's exact test

For binary or multi-class clinical features (nominal or ordinal), two-tailed Fisher's exact tests (Fisher 1922) were used to estimate the P values using the 'fisher.test' function in R

Q value calculation

For multiple hypothesis correction, Q value is the False Discovery Rate (FDR) analogue of the P value (Benjamini and Hochberg 1995), defined as the minimum FDR at which the test may be called significant. We used the 'Benjamini and Hochberg' method of 'p.adjust' function in R to convert P values into Q values.
