The QBiC-Pred web server for quantitative predictions of transcription factor binding changes due to sequence variants

QBiC-Pred is a web server that uses OLS 6-mer models trained on universal PBM data to predict TF binding changes due to sequence variants, as well as the significance of the changes (which implicitly depends on the quality of the data and models).

The iMADS web server for modeling and analysis of TF-DNA binding specificity and differential specificity

iMADS (integrative Modeling and Analysis of Differential Specificity) is a combined computational-experimental strategy to identify and study the differences in DNA-binding specificity between transcription factor (TF) family members, i.e. paralogous TFs.

Couger: CO-factors associated with Uniquely-bound GEnomic Regions:

COUGER implements a classification-based approach that can be applied to any two sets of genomic regions bound by paralogous TFs (e.g., regions derived from ChIP-seq experiments) to identify putative co-factors that provide specificity to each TF.
