    <summary type="html">Clashlist is a simple UNIX script which uses the awk facility along with&#xA;&#x9;the programs Probe and Cluster to build lists of van der Waals clashes&#xA;&#x9;from an input PDB-format molecular data file (with H atoms). These lists&#xA;&#x9;are organized such that collections of interacting residues are grouped&#xA;&#x9;together, sorted by the worst clash. For the purposes of this analysis,&#xA;&#x9;a clash is defined as a van der Waals overlap &amp;gt;= 0.4 A.</summary>

Indeed, if you get the&#xA;  format description (from anonymous ftp to ftp.pdb.bnl.gov, the file&#xA;  /pub/format.desc.ps) they show the single input line needed to read&#xA;  each record type.&#xA;  However, I am a C/C++ programmer in the Unix environment.  It is a&#xA;  easier for me to deal with field based input than column based ones.&#xA;  If the fields are white space delimited I can easily use awk and perl&#xA;  to manipulate the coordinate information.  So I needed some way to&#xA;  convert the ATOM and HETATM records of PDB files from the standard&#xA;  column based format to a field based one and back again.

An optimal alignment between two&#xA;  proteins, as well as the TM-score, will be reported for each comparison. The&#xA;  value of TM-score lies in (0,1]. In general, a comparison of TM-score smaller&#xA;  0.2 indicates that there is no similarity between two structures; a TM-score&#xA;  greater 0.5 means the structures share the same fold.&#xA;&#xA;  What is the difference between TM-score and TM-align?

The&#xA;  TM-align is a structural alignment program for comparing two proteins whose&#xA;  sequences can be different. The TM-align will first find the best equivalent&#xA;  residues of two proteins based on the structure similarity and then output a&#xA;  TM-score.

    <summary type="html">A fortran program in which Tirion&amp;#39;s model (also called the Elastic Network&#xA;  Model) is implemented. Within the frame of this model, atoms (particles)&#xA;  less than cutoff (angstroms) away from each others are linked by springs of&#xA;  same strength. Alternatively, a list of interacting atoms can be given to the&#xA;  program.&#xA;  Requirements: a file with the coordinates of the system, in PDB (Protein Data&#xA;  Bank) or &amp;#34;x y z mass&amp;#34; format.&#xA;&#xA;  Output: the hessian (the mass-weighted second derivatives of energy matrix),&#xA;  in the &amp;#34;i j non-zero-ij-matrix-element&amp;#34; format.&#xA;&#xA;  Diagstd, a fortran program with a standard diagonalization routine, can next&#xA;  be used in order to obtain the corresponding normal modes of the system. If&#xA;  the system is large, the RTB approximation can prove usefull (see below).</summary>
