MinCED - Mining CRISPRs in Environmental Datasets MinCED is a program to find Clustered Regularly Interspaced Short Palindromic Repeats (CRISPRs) in full genomes or environmental datasets such as assembled contigs from metagenomes. Iff you want to identify CRISPRs in raw short read data, in the size range of 100-200bp try using Crass (https://github.com/ctskennerton/Crass) MinCED runs from the command-line and was derived from CRT (http://www.room220.com/crt/): Charles Bland et al., CRISPR Recognition Tool (CRT): a tool for automatic detection of clustered regularly interspaced palindromic repeats, BMC Bioinformatics 8, no. 1 (2007): 209. INSTALLATION You need to install these dependencies first: * Java (http://www.java.com/en/download/) there is a Makefile in the source directory so installation should be as simple as: $ cd <download_folder> $ make To run MinCED: $ ./minced [options] file.fa The help page can be obtained by typing: $ ./minced --help You can get the MinCED version this way: $ ./minced --version NOTE: Always keep `minced` and `minced.jar` in the same folder! EXAMPLES Finding CRISPRs in the E. coli genome: $ minced ecoli.fna To find repeats in short sequences, we need to decrease the minimum number of repeats to find. For example, in 100 bp reads, we could not possibly find more than 2 repeats: $ minced -minNR 2 metagenome.fna The output can be large, so save it in a file: $ minced -minNR 2 metagenome.fna metagenome.crisprs COPYRIGHT AND LICENSE Copyright 2011 Florent ANGLY <firstname.lastname@example.org> 2013-2018 Connor SKENNERTON <email@example.com> MinCED is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
