Databases
The database for a
search
can be one or more structures; it is specified by a
STRUCTS option
.
For larger databases,
C-alpha
(
.cal
) or
binary C-alpha
formats are recommended; binary C-alpha (
.bca
) is the smallest and fastest to load.
See
file format conversion
for how to create
.cal
and
.bca
files.

~20% of taxonomy annotations in SILVA and Greengenes are wrong (
paper
).
Taxonomy prediction is <50% accurate for 16S V4 sequences (
paper
).
97% OTU threshold is wrong for species, should be 99% for full-length 16S, 100% V4 (
paper
).
