Method Detail

addOtuNode

public void addOtuNode(OtuNode node)
                throws Exception

Description copied from interface: ParserModule

Each sample with taxonomic assignments from a ClassifierModule is parsed by ParserModule.parseSamples() to produce a ParsedSample. As each file is processed, this method is called to add the OtuNode to the ParsedSample with the same sample ID (if valid).

Specified by:

addOtuNode in interface ParserModule

Parameters:

node - OtuNode

Throws:

Exception - if unable to add the OTU node

buildOtuCountFiles

public void buildOtuCountFiles()
                        throws Exception

Description copied from interface: ParserModule

After ParserModule.parseSamples() completes, this method builds the OTU count files.

Specified by:

buildOtuCountFiles in interface ParserModule

Throws:

Exception - if error occurs while building OTU tables

checkDependencies

public void checkDependencies()
                       throws Exception

Execute validateModuleOrder() to validate module configuration order.

Specified by:

checkDependencies in interface BioModule

Overrides:

checkDependencies in class ScriptModuleImpl

Throws:

Exception - thrown if missing or invalid dependencies are found

getParsedSample

public ParsedSample getParsedSample(String sampleId)

Description copied from interface: ParserModule

After ParserModule.parseSamples() completes, this method can be called to get a ParsedSample by its sample ID.

Specified by:

getParsedSample in interface ParserModule

Parameters:

sampleId - Sample ID

Returns:

ParsedSample with the given sampleId

getSummary

public String getSummary()
                  throws Exception

Produce summary message with min, max, mean, and median number of reads.

Specified by:

getSummary in interface BioModule

Overrides:

getSummary in class ScriptModuleImpl

Returns:

Summary of BioModule execution

Throws:

Exception - if any error occurs

parseSamples

public abstract void parseSamples()
                           throws Exception

Description copied from interface: ParserModule

Parse ClassifierModule output to build ParsedSamples.

Specified by:

parseSamples in interface ParserModule

Throws:

Exception - if error occurs while parsing classifier reports

runModule

public void runModule()
               throws Exception

Parsers execute a task with 3 core functions:

1. parseSamples() - generates ParsedSamples
2. buildOtuCountFiles() - builds OTU tree tables from the ParsedSamples

Specified by:

runModule in interface JavaModule

Specified by:

runModule in class JavaModuleImpl

Throws:

Exception - thrown if any runtime error occurs

isValid

protected boolean isValid(OtuNode node)
                   throws Exception

Some ClassifierModules can include taxonomy level identifiers without an OTU name in the sample report files. This method verifies the node exists, has a valid sample ID, and that no empty String OTU names are reported.

Parameters:

node - OtuNode build from 1 line of a ClassifierModule output file

Returns:

boolean if OtuNode is valid

Throws:

Exception - if errors occur checking if node is valid

validateModuleOrder

protected void validateModuleOrder()
                            throws Exception

Validate that no biolockj.module.seq modules run after this parser unless a new classifier branch is started.

Throws:

Exception - if modules are out of order

getDepricatedOtuCountFields

public static Set<String> getDepricatedOtuCountFields()

Getter for depricatedOtuCountFields

Returns:

depricatedOtuCountFields

getOtuCountField

public static String getOtuCountField()

Getter for otuCountField

Returns:

otuCountField

setNumHitsFieldName

public static void setNumHitsFieldName(String name)
                                throws Exception

When a module modifies the number of hits, the new counts must replace the old count fields.

Parameters:

name - Name of new number of hits metadata field

Throws:

Exception - if null value passed
