Prepare a Manifest

When preparing a run manifest, start with a template or create and populate an original CSV file. Element recommends at least completing the Settings and Samples sections.

CSV File Format

A CSV run manifest has a plain text format that supports multiple sections and metadata. For more information on the CSV file format, see the CSV file format specifications.

  • Valid run manifests are encoded in Unicode transformation format, 8-bit (UTF-8).
  • The maximum line length is 2048 characters. The line delimiter is “\n” or “\r\n”.
  • Blank lines and lines starting with the number sign (#) are valid but skipped.
  • Quotation marks (“ ”) optionally enclose field names that contain commas. The quotation marks prompt the software to include the comma and process the field as one entry.

Start from a Template

  1. Download a template.
  2. Open the template in Excel or a text editor, such as Notepad.
  3. Edit the template as desired: modify headings, modify metadata, and add columns.
  4. Save the run manifest as a CSV UTF-8 file in an AVITI OS-accessible location.
    • Use a preferred file name.
    • Do not include spaces in the file name.
