=== RegularMotifs ===
<code>RegularMotifs(regex&#58; Value) -&gt; PatternSeq</code><br/>
''Identifies regular motifs. The protein is split into individual chains and the residues are sorted by their Sequence Number before the motifs are identified. The query does not check if adjacent residues have consecutive Sequence Numbers. The query works in two modes: Amino and Nucleotide, on amino acids and nucleotides respectively. In the Amino mode, all the derivatives of standard residues are treated as the standard residues, as long as this information is properly annotated in MODRES or _pdbx_struct_mod_residue field. The default mode is 'Amino'''<br/>
;Arguments
: regex&#58; Value - ''Regular expression on one letter abbreviations of amino acids.'' 
;Options
: Type&#58; String = "Amino" - ''Determines the type of the query. Allowed values: Amino, Nucleotide.'' 
;Examples
: <code>RegularMotifs("RGD")</code>
:: ''Finds all RGD motifs.''
: <code>RegularMotifs("ACGTU", Type = 'Nucleotide')</code>
:: ''Finds all consecutive occurrences of the ACGTU nucleotides.''
: <code>RegularMotifs(".HC.").Filter(lambda m: m.IsConnected())</code>
:: ''Finds all 4 residue motifs with ?-HIS-CYS-? that are connected.''
