Concerning the magnitude of potency differences, there is no generally applicable rule for the definition of activity cliffs.
We decided against aggregating different definitions of SCAP, in an attempt to limit heterogeneity, and computed the performances of the prediction rules for the different definitions of SCAP.
The VFC Director (SEF) and programmer (LL) translated the rules for the defect definitions and the general rules into a point-by-point set of algorithms applied using logical statements included with standard Excel software (computer-based expert system).
This editor allows building, editing and validating a growing chemical ontology using the SMARTS and SMILES rules described above for the definition of compound classes.
These studies provide insights into the basic regulatory mechanisms of this step of eukaryotic gene expression contributing to a better knowledge of the rules for exon definition.
Using strict rules for homology definition, around half of the predicted genes in the grape genome are specific for grape [ 9], leading to the conclusion that some of the significant metabolic pathways for grape might not be easily inferred by homology transfer.
Cases of a specific condition were identified based on the information available in this data set and using different rules for case definition as discussed in the next section.
The latter lacks specificity, since many genes in genomic islands may have little to do with host interactions, and the definition of rules for the distribution across organisms can be arbitrary.
Alongside this work, [4] discusses how computer-assisted presentation of case data can help experts to infer machine-implementable rules for case definition in electronic health records.
Moreover, it employs concise representations of such distributions, called synopses, for the definition of rules that enable similarity searching optimization.
