Hello Kevin,

This particular function is like a "cat" - will work any text file. Assuming that you run the function in the same order the data was split, it should merge fine.

Should you want to work with tools that manipulate FASTQ files specifically, a tool search of "FASTQ" will bring up most plus look under the tool group "NGS: QC and manipulation -> Generic FASTQ manipulation".

And in case you didn't see this, data can be uploaded using FTP. Several compressed formats are support. Using a desktop client can the track progress of, restart, and confirm a load. http://galaxyproject.org/wiki/Learn/Upload%20via%20FTP

Best wishes for your project,

Jen Galaxy team

Hi Jennifer, just out of curiousity, is the command a linux cat? or does it actually parse the fastq sequences? asking as my service provider actually just split my PE files by lines (not no. of reads ) in fastq

assuming that I can't merge them in galaxy, I am merging them properly then splitting them again (anyway i can map using concurrent processes and merged the bam later on

Cheers Kevin

Hi Tracy,

The tool "Text Manipulation -> Concatenate datasets tail-to-head"
can put the two together. Then set the datatype to fastq, if needed
(click on the "pencil" icon for the full dataset to reach the "Edit
Attributes" form to make the change).

Be sure to watch out for an extra newline being added between the
two files. You can test for/eliminate this using "Filter and Sort ->
Select" with the options "that: NOT Matching" and "the pattern: ^$".
(the regular expression '^$' [no quotes] matches empty lines).

I am sending to the galaxy-user mailing list for our internal
tracking and for other users to learn from. Please send all
questions directly to the list going forward, it is very helpful for us.

Thanks for using Galaxy!
