Table 2 provides the exact identifiers of the data sets.
MMM was able to identify an exact concept identifier (CUI) from the UMLS for over 50% of 'cause of death' phrases.
In addition, since records with variations of identifiers may have different characteristics to records with exact matching identifiers, restricting the linkage in this manner is not an option.
For all tasks, we considered only strict correspondence between the expected GO terms (i.e. gold file) and the evaluated answers: the systems had to output the exact GO identifiers, and no hierarchic or semantic similarities were tolerated in the evaluation (29).
In order to obtain only specific CNGC sequences, we removed the hits with exact duplicates (same identifiers, same sequence and different identifiers, same sequence), annotated fragments, as well as any unrelated gene like AKT or KAT family channels from subsequent analyses (Additional file 9).
Since these protocols require exact matching of identifiers, they do not tolerate any errors in these identifiers: Due to the design specifications of cryptographic functions, the slightest input variation results in many changes to the output (ideally, a change of one input bit should cause a change in half of the output bits).
Perhaps a linkage system that best serves the demands of epidemiological research in the future could readily incorporate a combination of exact matching on universal identifier corroborated by probability matching techniques on the traditional identifiers.
Boxplots of raw amplicon reads of the libraries, which refer to sequence reads filtered by an exact primer or multiplex identifier sequence (MID) match, are shown in Figure 1.
The MF data were linked using exact matching of unique identifiers to the Cause of Death Register (Statistics Finland) and the Hospital Care Register National Research and Development Centree for Welfare and Health).
In order to transfer binding site information in the future, we need to translate the position on the original sequence to the updated sequence or make sure that ID mapping adds only identifiers representing the exact same sequence.
