Input options. Options are separated into sequence masking, SLiMBuild motif construction and SLiMChance/Output filtering. For clarity, all options correspond to commandline parameters of downloadable SLiMFinder program; short descriptions and commandline parameter names are given if the mouse hovers over the help buttons. All options are described in the help pages. Once options have been set/reviewed, ‘Submit job’ will move the job into the run queue.
