Using Cannoli interactively from the shell

To run the Cannoli interactive shell, based on the ADAM shell, which in turn extends the Apache Spark shell, use cannoli-shell.

Wildcard import from ADAMContext to add implicit methods to SparkContext for loading alignments, features, fragments, genotypes, reads, sequences, slices, variant contexts, or variants, such as sc.loadPairedFastqAsFragments below.

Wildcard import from Cannoli to add implicit methods for calling external commands to the genomic datasets loaded by ADAM, such as reads.alignWithBwaMem below.

$ ./bin/cannoli-shell \
    <spark-args>

scala> import org.bdgenomics.adam.ds.ADAMContext._
import org.bdgenomics.adam.ds.ADAMContext._

scala> import org.bdgenomics.cannoli.Cannoli._
import org.bdgenomics.cannoli.Cannoli._

scala> import org.bdgenomics.cannoli.BwaMemArgs
import org.bdgenomics.cannoli.BwaMemArgs

scala> val args = new BwaMemArgs()
args: org.bdgenomics.cannoli.BwaMemArgs = org.bdgenomics.cannoli.BwaMemArgs@54234569

scala> args.indexPath = "hg38.fa"
args.indexPath: String = hg38.fa

scala> args.sampleId = "sample"
args.sampleId: String = sample

scala> val reads = sc.loadPairedFastqAsFragments("sample1.fq", "sample2.fq")
reads: org.bdgenomics.adam.ds.fragment.FragmentRDD = RDDBoundFragmentRDD with 0 reference
sequences, 0 read groups, and 0 processing steps

scala> val alignments = reads.alignWithBwaMem(args)
alignments: org.bdgenomics.adam.ds.read.AlignmentRecordRDD = RDDBoundAlignmentRecordRDD with
0 reference sequences, 0 read groups, and 0 processing steps

scala> alignments.saveAsParquet("sample.alignments.adam")

Running Cannoli from the command line

To run Cannoli commands from the command line, use cannoli-submit.
