+**What it does**
+
+This tool selects random records from a file. Each record is defined by a fixed number of lines.  
+
+- When doing over-sampling,  --replacement  option is enforced by default.
+

+
+**Example 1: sampling from a BED file**
+
+parameters::
+
+    1 line per record, sampling 5 lines, without replacement, output line 1 (track name) directly
