ewels / find_uncompressed_files.pl
Created August 7, 2013 16:28
In bioinformatics, raw ASCII text file can get massive. This script sniffs out large uncompressed text files and sends their paths to STDOUT for piping to a file or zipping command.
#/usr/bin/perl
use warnings;
use strict;
use Cwd;
use File::Find;
####
# FIND UNCOMPRESSED FILES
# Prints the full path of any files larger than 50mb which are uncompressed
# One file path per newline, so output can be piped to other tools, eg:
# perl find_uncompressed_files.pl | xargs gzip

Quick and dirty script to check for common warning signs in a Bismark BS-seq methylation analysis
#!/bin/bash
# Check bisulfite analysis results for any modes of failure that I can think of.
# Assumes data is processed by Cluster Flow / bismark and is in subdirectories.
# For a basic quick summary, just run:
# bash check_bismark_analysis.sh
# To filter which subdirectories are checked, pass a glob expression. For example:
# bash check_bismark_analysis.sh run2_*
