Glad to hear it, who doesn't like support or clean interfaces?. No offense intended, by the way, with respect to PDB errors - obviously the PDB is an indispensable resource for all protein scientists.
I am looking at many (fixed-length) pieces of protein chains and doin' stuff with 'em. My current code has a pair of nested while loops; the outer iterates over PDB entries (locally rsync'd copy), parsing them and the inner iterates over the pieces from each. When StructureExceptions come out of my PDBFileReader object I want to continue the outer loop, moving on to the next set of files without executing any of the code that depends on correct StructureImpl objects from the reader (database updates, the inner loop). Since the reader's methods have their own try-catch blocks, a thrown StructureException is stopped there and never reaches my own error handling. I just need to know when those errors occur so I can skip those proteins - I am presuming that the correct entries will outweigh the problem ones by a significant factor and the overall data wont be seriously impacted. -da On Tue, Oct 26, 2010 at 21:11, Andreas Prlic <[email protected]> wrote: > Hi Daniel, > > can you explain a bit more what you are doing, in particular what > errors you would like to deal with on your end?
