If you chose Exome and Gene Panel from the Choose Assembly Workflow screen, you may import a targeted regions file.
Manifest files are tab-separated files used to define the chromosomal coordinates of gene targets in the assembly, and can be made by hand or automatically generated, e.g., by Illumina. (See Illumina’s manifest file PDF for a description.) Manifest files can have various file extensions, though .txt is commonly used.
The following examples show the most basic required columns for the manifest file, as well as two formats that are used by Illumina. These examples are provided in case you need to trouble-shoot problems with existing manifest files. If you want to create your own targeted regions file, we recommend making a BED file rather than a manifest file. See Make a Custom BED File for detailed instructions.
Note: The columns below can appear in any order. Columns with pink headers are required, while columns with green headers are optional

Note: SeqMan NGen can read and produce output using a variety of common chromosome naming conventions, including “chr1” and “ch1,” as well as Arabic and Roman numerals. Chromosome names are captured from genome template packages and used to assign contig IDs to entries from BED, VCF and manifest files.
