Supplementary Information for the Manuscript

·        Although MatAlign also employs two-level dynamic programming as in SSAP (Taylor and Orengo, JMB 208, 1989), it is substantially different from SSAP.  (See details in Pdf)

 

·        MatAlign performs better than DALI and CE in terms of 4 alignment quality criteria in a majority of cases.  (See detailed results in MS Excel)

 

·        When the alignment lengths are set to be equal, MatAlign’s RMSD is still better in a majority of cases.  (See detailed results in MS Excel)

 

·        Classification Experiment at Super Family Level (20 query proteins against 200 database proteins).  (Download dataset in MS Excel)  (See detailed results in MS Excel)
