Method Detail

getReferenceSequenceFile

public static ReferenceSequenceFile getReferenceSequenceFile(java.io.File file)

Attempts to determine the type of the reference file and return an instance of ReferenceSequenceFile that is appropriate to read it. Sequence names will be truncated at first whitespace, if any.

Parameters:

file - the reference sequence file on disk

getReferenceSequenceFile

public static ReferenceSequenceFile getReferenceSequenceFile(java.io.File file,
                                             boolean truncateNamesAtWhitespace)

Attempts to determine the type of the reference file and return an instance of ReferenceSequenceFile that is appropriate to read it.

Parameters:

file - the reference sequence file on disk

truncateNamesAtWhitespace - if true, only include the first word of the sequence name

getReferenceSequenceFile

public static ReferenceSequenceFile getReferenceSequenceFile(java.io.File file,
                                             boolean truncateNamesAtWhitespace,
                                             boolean preferIndexed)

Attempts to determine the type of the reference file and return an instance of ReferenceSequenceFile that is appropriate to read it.

Parameters:

file - the reference sequence file on disk

truncateNamesAtWhitespace - if true, only include the first word of the sequence name

preferIndexed - if true attempt to return an indexed reader that supports non-linear traversal, else return the non-indexed reader
