Name	Type	Attributes	Definition
sequence_id	string	required, identifier, nullable	"Unique query sequence identifier within the file. Most often this will be the input sequence header or a substring thereof, but may also be a custom identifier defined by the tool in cases where query sequences have been combined in some fashion prior to alignment.
"
segment	string	required, nullable	"The segment for this alignment. One of V, D, J or C.
"
rev_comp	boolean	optional, nullable	"Alignment result is from the reverse complement of the query sequence.
"
call	string	required, nullable	"Gene assignment with allele.
"
score	number	required, nullable	"Alignment score.
"
identity	number	optional, nullable	"Alignment fractional identity.
"
support	number	optional, nullable	"Alignment E-value, p-value, likelihood, probability or other similar measure of support for the gene assignment as defined by the alignment tool.
"
cigar	string	required, nullable	"Alignment CIGAR string.
"
sequence_start	integer	optional, nullable	"Start position of the segment in the query sequence (1-based closed interval).
"
sequence_end	integer	optional, nullable	"End position of the segment in the query sequence (1-based closed interval).
"
germline_start	integer	optional, nullable	"Alignment start position in the reference sequence (1-based closed interval).
"
germline_end	integer	optional, nullable	"Alignment end position in the reference sequence (1-based closed interval).
"
rank	integer	optional, nullable	"Alignment rank.
"
rearrangement_id	string	DEPRECATED	"Identifier for the Rearrangement object. May be identical to sequence_id, but will usually be a universally unique record locator for database applications.
"
data_processing_id	string	optional, nullable	"Identifier to the data processing object in the repertoire metadata for this rearrangement. If this field is empty than the primary data processing object is assumed.
"
germline_database	string	DEPRECATED	Source of germline V(D)J genes with version number or date accessed.
