PDF-4 Software

NOTICE - This document includes dated information and numbers - NOTICE


ICDD's data mining software is integrated into all PDF products. This software provides more display, search, and data filtering capabilities for the PDF-4 format of the Powder Diffraction File. The program contains 72 different search methods to filter the database contents with custom display of a selection of 125 separate data fields. Using a Java™ point and click interface, various search methods and field selections can be combined to produce a nearly limitless choice of data mining options. Search criteria in our data mining software can also be used to focus the results of SIeve+ search-indexing onto user-defined subsets of PDF entries.

SIeve+ 2018 - Purchase
SIeve+ provides rapid searching and identification of materials using highly automated Hanawalt, Fink and Long-8 searches. SIeve+ takes advantage of the dynamic computing power of modern PCs to rapidly perform permuted searches on hundreds of thousands of data entries. This enables Fink and Long-8 algorithms that are impractical with print, due to their enormous size with permutation. A new feature for this release is automatic rotation of the  8 strongest lines (Hanawalt) or the 8 longest of the strongest lines (Fink) or the 8 long lines (Long 8) to look for matches that exhibit the best Goodness of Match (GOM). Historically, these rotation operations were anticipated and integrated into paper manual search-index method protocols; they can be switched on/off in SIeve+ using the Preferences function. The paper manual search schema always offers a litmus test for searching, namely that all the lines in the unknown pattern must be matched against all the lines in the reference pattern(s). To address this comparison, we have implemented a “Pattern GOM” that provides this comparison. The SIeve+ display allows a comparison between the standard GOM and the Pattern GOM. Extensive digitized data plotting functions allow comparisons between experimental data and SIeve+ search match results.

SIeve+ works with either input d/I pairs or electronic files that contain d or two-theta/I data. A flexible text importer can read a wide variety of input files; any number of d/I pairs can be imported. SIeve+ is linked with Global searches and Search Preferences from our integrated software. This means that a user can custom define a SIeve+ input filter based on any of the 72 search method classes or combinations thereof. The results of SIeve+ can also be integrated into search criteria in our viewing software.
