        assert scriptFile

        // start session
        session.start()

nextflow数据类型

nextflow的数据类型包括 queue channels、value channels。

DataflowBroadcast、DataflowQueue、DataflowVariable

A value channel is created using the value factory method or by operators returning a single value

println Channel.fromSRA(['SRR8924749', 'SRR6326268 ', 'ERR908505'])
println Channel.from( 1, 3, 5, 7 )
println Channel.fromPath( 'download.csv' )
println Channel.value( 'Hello there' )
DataflowQueue(queue=[])
DataflowBroadcast around DataflowStream[?]
DataflowBroadcast around DataflowStream[?]
DataflowVariable(value=null)

创建Channel

使用SRA获取fastq文件
函数fromSRA可以从SRA获取数据

ch_sra = Channel.fromSRA(['SRR8924749', 'SRR6326268', 'ERR908505'])
ch_sra.view()

首选需要构建一个查询对象

def target = new DataflowQueue()
def explorer = new SraExplorer(target, opts).setQuery(query)

接下来执行查询操作

session.addIgniter { fetchSraFiles0(explorer.apply()) }

explorer.apply()执行query0绑定数据

    DataflowWriteChannel apply() {
        query0(query)
		
        target.bind(Channel.STOP)
        return target
    }

query0主要执行target.bind( [acc, files] )进行绑定

void query0(){
	target.bind( [acc, files] )
}

从mysql创建Channel

ch_qu = channel.fromQuery('select run_id from seqdata where is_check =TRUE', db: 'foo').take(10)

创建handler对象

final channel = CH.create()
final dataSource = dataSourceFromOpts(opts)
final handler = new QueryHandler()
	.withDataSource(dataSource)
	.withStatement(query)
	.withTarget(channel)
	.withOpts(opts)

执行查询

session.addIgniter {-> handler.perform(true) }

handler.perform(true)可以进行异步和同步的查询

QueryHandler perform(boolean async=false) {
	final conn = connect(dataSource ?: SqlDataSource.DEFAULT)
	if( async )
		queryAsync(conn)
	else
		queryExec(conn)
	return this
}
 QueryHandler perform(boolean async=false) {
        final conn = connect(dataSource ?: SqlDataSource.DEFAULT)
		queryAsync(conn)
        return this
    }

queryAsync主要执行对数据的绑定

try {
	target.bind(item)
}finally {
	target.bind(Channel.STOP)
}

Operator函数的源码解读

使类用nextflow.extension.OperatorImpl的类有
nextflow.plugin.extension.PluginExtensionProvider

    private Set<String> loadDefaultOperators() {
        final result = getDeclaredOperatorExtensionMethods0(OperatorImpl.class, true)
        for( String it : result )
            operatorExtensions.put(it, new PluginExtensionMethod(method: it, target: OperatorImpl.instance))
        return result
    }
    protected PluginExtensionProvider loadPluginExtensionMethods(String pluginId, PluginExtensionPoint ext, Map<String, String> includedNames){
        // find all operators defined in the plugin
        final definedOperators= getDeclaredOperatorExtensionMethods0(ext.getClass())
        // find all factories defined in the plugin
        final definedFactories= getDeclaredFactoryExtensionMethods0(ext.getClass())
        // find all functions defined in the plugin
        final definedFunctions= getDeclaredFunctionsExtensionMethods0(ext.getClass())

groovy脚本

nextflow.splitter.SplitterEx

def sample = file('/data/sample.txt')
println sample.countLines()
static long countLines(Path self, Map opts=EMPTY) {
	new TextSplitter().options(opts) .target(self) .count()
}

BaseScript

private void setup() {
        binding.owner = this
        session = binding.getSession()
        processFactory = session.newProcessFactory(this)

        binding.setVariable( 'baseDir', session.baseDir )
        binding.setVariable( 'projectDir', session.baseDir )
        binding.setVariable( 'workDir', session.workDir )
        binding.setVariable( 'workflow', session.workflowMetadata )
        binding.setVariable( 'nextflow', NextflowMeta.instance )
        binding.setVariable('launchDir', Paths.get('./').toRealPath())
        binding.setVariable('moduleDir', meta.moduleDir )
    }

    protected process( String name, Closure<BodyDef> body ) {
        if( NF.isDsl2() ) {
            def process = new ProcessDef(this,body,name)
            meta.addDefinition(process)
        }
        else {
            throw new UnsupportedOperationException("DSL1 is not supported anymore")
        }
    }
