Hello,
What is the difference between "Concatenate datasets tail-to-head" under "Text Manipulation" and "Concatenate two datasets into one dataset" under "Operate on Genomic Intervals" I'm having trouble understanding the difference and when I apply it to my mapped reads for ChIP seq analysis which are SAM files but could also be formatted to interval files, only Text Manipulation works but operate on genome intervals does work. Could someone explain this difference please? Thank you .
Tool name: Concatenate datasets
Tool version: 1.0.0
