+**What it does**
+
+bedtools slop will increase the size of each feature in a feature file by a user-defined number of bases. While something like this could be done with an awk '{OFS="\t" print $1,$2-&lt;slop>,$3+&lt;slop>}', bedtools slop will restrict the resizing to the size of the chromosome (i.e. no start &lt; 0 and no end > chromosome size).

+
+In order to prevent the extension of intervals beyond chromosome boundaries, bedtools slop requires a genome file defining the length of each chromosome or contig.
