It was initially designed (\s-1JASPAR2\s0) to store matrices for the \s-1JASPAR\s0 database of high quality eukaryotic transcription factor specificity profiles by Albin Sandelin and Wyeth W. Wasserman. Besides the profile matrix itself, this data model stores profile \s-1ID\s0 (unique), name, structural class, basic taxonomic and bibliographic information as well as some additional, and custom, tags. .PP Here goes a moore thorough description on tables and IDs .PP \&\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- \s-1ADVANCED\s0 \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- .PP For the developers and the curious, here is the \s-1JASPAR5\s0 data model: .PP \&\s-1MISSING TEXT HEER ON HOW IT WORKS\s0 .PP It is our best intention to hide the details of this data model, which we are using on a daily basis in our work, from most \s-1TFBS\s0 users.
