Hi Felix,

"Text Manipulation -> Convert delimiters to TAB" could split one field into more than one, but the delimiter has to be in the list ("@" is not).

"Text Manipulation -> Cut columns" from a table is similar, but it will not split on a "@" either.

"Text Manipulation -> Trim leading or trailing characters" could be use for this specific case, since you can trim off the end of a column based on a position (but again, not a specified delimiter). To prep for an entire genome, you would need to break up the starting query so that the chromosome name lengths in any derivative queries are of a consistent length, then merge back together.

Perhaps the "@" was just an example and one of these tools will work for you. If you are customizing, additions to the Tool Shed that expand the native tools are always welcome! http://community.g2.bx.psu.edu

Thanks for using Galaxy and for bringing up an interesting use case,

Best,

Jen

Hi,
is there a way to manipulate the different values in the column of a tab
sepparated file (i.e. change all chr1@sdfasdfasdfasdf to chr1 using
regexp).
thx,
Felix
