Can the PV 'Find Data…' command be used to search attribute data of type string? The specific case I have is the Protein Data Bank Reader which returns the point data attribute called 'atom_types'. It contains atom names such as 'N' or 'C' or 'O' etc. I'd like to search and extract point data based on the 'atom_types' string. For example atom_types == 'O' - but this returns an error (see below). Any help or pointers greatly appreciated. Joe Young.
P.S. The specific error code is: Traceback (most recent call last): File "<string>", line 8, in <module> File "<string>", line 5, in vtkPythonExtractSelection_RequestData File "/Applications/paraview_4_3_1.app/Contents/Python/paraview/extract_selection.py", line 88, in execute (query, type(maskArray)) RuntimeError: Expression 'atom_types == 'O'' did not produce a valid mask array. The value produced is of the type '<type 'bool'>'. This typically implies a malformed expression. Verify that the expression is valid. ---- Dr Joseph Young Queensland University of Technology | Australia www.qut.edu.au | [email protected]<mailto:[email protected]> CRICOS No. 00213J
