== Use of the FastQFile class ===
Generally this class is used to read a fastq file and perform operations on the sequences.
Here is an example of how this would be done.
bool <yourMethod>()
String filename = <your filename>;
// Open the fastqfile.
if(openFile(filename, spaceType) != FASTQ_SUCCESS)
// Failed to open the specified file.
// Report the error and exit (handled by error).
error("Failed to open file: %s", filename.c_str());
return (false);
// Keep reading the file until there are no more fastq sequences to process.
while (!ifeof(myFile))
// Read one sequence. This call will read all the lines for
// one sequence.
FastQFile::FastQStatus = readFastQSequence;
// NOTE: It is up to you if you want to process only for success:
// if(readFastQSequence() == FASTQ_SUCCESS)
// if(readFastQSequence() != FASTQ_FAILURE)
// Do NOT try to process on a FASTQ_FAILURE
if(readFastQSequence() == FASTQ_SUCCESS)
// The sequence is valid.
<Your Processing Here>
// Finished processing all of the sequences in the file.
// Close the input file.
return(true/false); // It is up to you to determine what is considered success/failure.
