Underlying RDD
Sequence dictionary computed from rdd
Performs a broadcast inner join between this RDD and another RDD.
Performs a broadcast inner join between this RDD and another RDD.
In a broadcast join, the left RDD (this RDD) is collected to the driver, and broadcast to all the nodes in the cluster. The key equality function used for this join is the reference region overlap function. Since this is an inner join, all values who do not overlap a value from the other RDD are dropped.
The right RDD in the join.
Returns a new genomic RDD containing all pairs of keys that overlapped in the genomic coordinate space.
Counts the k-mers contained in a FASTA contig.

Performs a sort-merge full outer join between this RDD and another RDD.
Performs a sort-merge full outer join between this RDD and another RDD.
In a sort-merge join, both RDDs are co-partitioned and sorted. The
partitions are then zipped, and we do a merge join on each partition.
The key equality function used for this join is the reference region
overlap function. Since this is a full outer join, if a value from either
RDD does not overlap any values in the other RDD, it will be paired with
a None in the product of the join.
The right RDD in the join.
Returns a new genomic RDD containing all pairs of keys that
overlapped in the genomic coordinate space, and values that did not
overlap will be paired with a None.
Fragment to extract a region from.
If a fragment is aligned to a reference location, returns a single reference region. If the fragment start position and name is not defined, returns no regions.

Performs a sort-merge left outer join between this RDD and another RDD.
In a sort-merge join, both RDDs are co-partitioned and sorted. The
partitions are then zipped, and we do a merge join on each partition.
The key equality function used for this join is the reference region
overlap function. Since this is a left outer join, all values in the
right RDD that do not overlap a value from the left RDD are dropped.
If a value from the left RDD does not overlap any values in the right
RDD, it will be paired with a None in the product of the join.

Pipes genomic data to a subprocess that runs in parallel using Spark.
Pipes genomic data to a subprocess that runs in parallel using Spark.
Files are substituted in to the command with a $x syntax. E.g., to invoke a command that uses the first file from the files Seq, use $0.
Pipes require the presence of an InFormatterCompanion and an OutFormatter as implicit values. The InFormatterCompanion should be a singleton whose apply method builds an InFormatter given a specific type of GenomicRDD. The implicit InFormatterCompanion yields an InFormatter which is used to format the input to the pipe, and the implicit OutFormatter is used to parse the output from the pipe.

A GenomicRDD containing X's.

Performs a broadcast right outer join between this RDD and another RDD.
In a broadcast join, the left RDD (this RDD) is collected to the driver,
and broadcast to all the nodes in the cluster. The key equality function
used for this join is the reference region overlap function. Since this
is a right outer join, all values in the left RDD that do not overlap a
value from the right RDD are dropped. If a value from the right RDD does
not overlap any values in the left RDD, it will be paired with a None
in the product of the join.

Saves Avro data to a Hadoop file system.
Saves Avro data to a Hadoop file system.
This method uses a SparkContext to identify our underlying file system, which we then save to.
Frustratingly enough, although all records generated by the Avro IDL compiler have a static SCHEMA$ field, this field does not belong to the SpecificRecordBase abstract class, or the SpecificRecord interface. As such, we must force the user to pass in the schema.
