When running a sequencing pipeline it is useful to know that your sequencing runs contain the types of sequence they're supposed to.

FastQ Screen allows you to set up a standard set of libraries against which all of your sequences can be searched. Your search libraries might contain the genomes of all of the organisms you work on, along with PhiX, Vectors or other contaminants commonly seen in sequencing experiments.

The program produces both text based and graphical output which summaries the mapping of your sequences against each of your libraries, so that when you search your mouse sequences you can see if they're good, like this:

A good screen result

..and not bad, like this:

A bad screen result
