Open Live Script

Import the pipeline, block, and library objects needed for the example.

import bioinfo.pipeline.library.*
import bioinfo.pipeline.block.*
import bioinfo.pipeline.Pipeline

Create a library and add it to the list of available libraries.

mylib = Library;
mylib.Name = "customLib";
addLibrary(mylib);

Create a FeatureCount block and a FileChooser block for a FASTQ file, that is provided with the toolbox and add to the library.

fcBlock = FeatureCount;
fastqfile = FileChooser(which("SRR005164_1_50.fastq"));

Add the blocks to the library. Name the blocks as "featurecount" and "fastqfile", respectively.

addBlock(mylib,fcBlock,"featurecount");
addBlock(mylib,fastqfile,"fastqfile");

Find a block by its name from the library.

b1 = findBlock(mylib,"featurecount")
b1 = 
  FeatureCount with properties:

         Options: [1×1 bioinfo.pipeline.options.FeatureCountOptions]
          Inputs: [1×1 struct]
         Outputs: [1×1 struct]
    ErrorHandler: []

You can also search for multiple blocks.

bArray = findBlock(mylib,["fastqfile","featurecount"]);
length(bArray)
ans = 
2

Rename the "featurecount" block to "fcBlock".

renameBlock(mylib,"featurecount","fcBlock");
mylib.BlockNames
ans = 2×1 string
    "fastqfile"
    "fcBlock"
