Dear all,
I would like to comapare the topology of two homologous chains
using top3d (to get residue by residue rms deviation). But TOPP
assigns secocndary structures to theses chains and compares only
those secondary structure to give average angle/distance deviations,
giving an output like this
---------------
222 Ca atoms read 0 helixes 17 strands in file a2C.pdb
1 chains in Mol2
Chain C Nr 1 17
----------------------------------------------------------------------
17 of ( 17, 17) secondary structure could be aligned
---------------------------------------------------+-----+-----+------
Nr.E Mol1 start end match Nr.E Mol2 start end !angle! dst ! r.m.s
---------------------------------------------------+-----+-----+------

---------------------
I would appreciate if any one can suggest any key word to be included
(or any other program) to get residue by residue rms deviation while
comapring two pdb files.
Thanks in advance
