call ToGvcf.VariantCalling as BamToGvcf {
input:
...
input_bam = UnmappedBamToAlignedBam.output_bam,
我们现在知道
VariantCalling
是在所导入的
WDL
文件中定义的一个工作流，该
call
块的意思是：
从所导入的叫作
ToGvcf
的那堆代码中，调用
VariantCalling
工作流，但是在主工作
流范围内，称其为
BamToGvcf
。
VariantCalling
工作流接受
BAM
格式输入文件，以
UnmappedBamToAlignedBam
工作流的输出作为其输入。
你可能注意到，上述代码对待
UnmappedBamToAlignedBam
和
VariantCalling
两
个工作流的方式有点不同，非常有趣的是：后者被赋予别名，而前者却没有。
UnmappedBamToAlignedBam
保留它在
WDL
文件被定义时使用的原名称。根据我们目
前所观察到的命名模式，我们猜测该工作流的编者希望在各个阶段根据主要输入和
输出文件的格式来识别程序的高层结构。这是基因组研究常用模式；该策略虽不是
最健壮的，但是很简洁，而且除了文件格式之外，研究者不需要太多领域知识，就
能理解文件主要用途。
总之，其实际后果是我们可以通过原名称或别名（前提是得有）指向子工作流的输出。
然而，需说明的是，我们只能指向子工作流中作为工作流层级输出的输出。如子工
作流中的任务没有在工作流层级声明，而仅在任务层级声明 ...
