IDR is an open source tool available on GitHub. It is a Python program that has already been installed on O2. The first thing we need to do is load the module (and all dependency modules) to run IDR: Now let’s move into the chipseq/resultsdirectory and create a new directory for the results of our IDR analysis. … See more The first step is taking our replicates and evaluating how consistent they are with one another. To run IDR we use the idrcommand followed by any necessary parameters. To see … See more Once you have IDR values for true replicates, you want to see how this compares to pooled replicates. This is a bit more involved, as it requires you to go back to the BAM … See more The user manual provides guidelines on IDR thresholdswhich are recommended for the different types of IDR analyses. Depending on the … See more An optional step is to create pseudo-replicates for each replicate by randomly splitting the reads and running them through the same workflow.
