Set the profile HMM database that your query will be searched against.
There are three different ways of controlling which HMMs match your query.
E-value:Control both significant and reporting thresholds for the model and each hit, 10≥x>0.May be entered with scientific notation.
Bit score:Control both significant and reporting thresholds for the model and each hit, x>0.
Gathering:Use the HMM database defined significance thresholds.
Use the gathering threshold.
Note: The Gene3D and Superfamily databases will ignore custom cut-off parameters since they use a post processing step that involves preset thresholds.
Under some circumstances, hits can be lost due to the fact a
sequence, or regions of a sequence, are omitted due to bias composition.
You can turn this filter off, but it will slow down your searches.
