PatternQuery:Language Reference

Introduction

MotiveQuery is a subset of the Python programming language. Therefore, if you have experience with it, it should not be a problem to use MQ as well.

• The language is case sensitive - "filter" is NOT the same as "FiLtEr".

Some of the functions return Motives while other only Motive.

• Motive is a set of atoms.
• Motives is a sequence of Motive (the sets of atoms).

When a molecule is queried, say using the expression Rings(5 * ["C"] + ["O"]) a sequences of motives each containing 6 atoms (5 C and 1 O) is returned. However, some functions such as Filter need to operate on a single motive (the set of atoms) - not the whole sequences. The query Filter(Residues(), lambda r: r.Count(Atoms()) > 10) first finds all residue Motives (sequence) and then passes every single Motive (set of atoms) to a function that counts the atoms in the motive and returns True if there is at least 11 of them. This is the reasoning behind these two types.

Using MotiveQuery in Silverlight applications

MotiveQuery can be used in SiteBinder, EEM Charges, and MotiveExplorer from the the corresponding UI elements. Moreover, it is possible to use MQ from the Scripting window. This is achieved using the MQ.Execute function. The function takes two parameters: the query and an optional target structure list.

Examples

These examples can be executed from the Scripting window of SiteBinder, MotiveExplorer, or other Silverlight applications.

q = Atoms("Zn").ConnectedAtoms(2) 
MQ.Execute(q)

This command finds all motifs specified by the query q in all loaded structures.

MQ.Execute(Residues("HEM"), [ Session.StructureMap["1tqn"], Session.StructureMap["2wer"] ])

This command finds all HEM residues in structures 1tqn and 2wer (provided structures with these names are loaded).

q = AtomSimilarity(Motive("model"), Motive("1gtz_0"))
MQ.Execute(q)

This command computes the atom similarity (Jaccard coefficient) for structures model and 1gtz_0.

q = ResidueSimilarity(Motive("model"), Current())
MQ.Execute(q, Session.Structures)

This command computes the residue similarity (Jaccard coefficient) for the structure with id 'model' (which is loaded using the Motive function) and all other loaded structures (computed one by one using the function Current()). The result is returned in CSV format.
