Hello Steve, Yes, this is true, many of the Interval Operations tools do not interpret strand. Meaning that you would need to first filter the data by strand, then perform the operation per strand to obtain an inner join result.

Hello, I using operate on genomic intervals on some data and it always seems to ignore the strand information. Am I missing something or does "operate of genomic intervals" disregard strand information? Is there a tool that does the inner join function and takes into account strand information?

thanks,

Steve
