JASPAR 2018 used the TFBS Perl module (Lenhard and Wasserman 2002) and FIMO (Grant, Bailey, and Noble 2011), as distributed within the MEME suite (version 4.11.2) (Bailey et al. 2009). For scanning genomes with the BioPerl TFBS module, profiles were converted to PWMs and matches were kept with a relative score ≥ 0.8. For the FIMO scan, profiles were reformatted to MEME motifs and matches with a p-value < 0.05 were kept. TFBS predictions that were not consistent between the two methods (TFBS Perl module and FIMO) were removed. The remaining TFBS predictions were colored according to their FIMO p-value to allow for comparison of prediction confidence between different profiles.

Limited regions can be explored interactively with the Table Browser and cross-referenced with Data Integrator, although positional queries that are too big can lead to timing out. This results in a black page or truncated output. In this case, you may try reducing the chromosomal query to a smaller window.
For programmatic access, the track can be accessed using the Genome Browser's REST API. JASPAR annotations can be downloaded from the Genome Browser's download server as a bigBed file. This compressed binary format can be remotely queried through command line utilities. Please note that some of the download files can be quite large.
