Welcome to the bioinformatics tools server

This is the entry page for all the bioinformatics tools offered by Ralf Bundschuh's statistical physics group at the Department of Physics of The Ohio State University. This page is still under construction. Below is a list of currently offered tools.

• the RNA pulling server: calculates force-extension curves of RNA and ssDNA molecules, taking into full account of their secondary structures based on the Vienna RNA package. See also Terry Hwa's server.
• the hybrid parameter estimator: estimates the parameters necessary to assign p-values to hybrid alignments.
• the hybrid PSI-BLAST server: performs protein sequence database searches with a version of PSI-BLAST that uses suboptimal alignments in model building to improve sensitivity over traditional PSI-BLAST
