 [Picard](https://broadinstitute.github.io/picard/) is a set of command line tools for **processing high-throughput sequencing (HTS) data and formats such as SAM/BAM/CRAM and VCF**. It is maintained by the Broad Institute, and is open-source under the MIT license and free for all uses. Picard is written in Java and does not have functionality for multi-threading.
 
 > ### Why not use `samtools`?
-> The processing of the alignment files (SAM/BAM files) can also be done with [`samtools`](https://github.com/samtools/samtools). While there are some advantages to using samtools (i.e. more user-friendly, multi-threading capability), there are slight formatting differences which can cause errors downstream. Since we will be using GATK later in this workshop (also from the Broad Institute), Picard seemed like a more suitable fit.
