The loadContaminant command loads a contaminant sequence file to be used to identify known contaminants, such as primers, in the assembly. Sequences that contain at least 12 matching 17-mers are flagged as contaminant sequences and will be removed from the assembly.

Parameter Description Allowed values
file The directory and file name of the contaminant sequence file. A folder may also be specified, in which case all of the sequence files within that folder will be loaded and used for contaminant screening. [directory/filename enclosed in quotes]


   file: “/Library/contaminants/123_abc.seq”
