From, click on the "Import Parts" button to bring in multiple parts simultaneously.  Currently, you can upload tab-delimited text files or FASTA files.  When using a tab-delimited text file it is important to 1) use the correct column order and 2) save text files as UTF-8 encoded text files (or Windows Formatted Text, if working in Microsoft Excel).

From left to right: 1) part name, 2) part category letter ID (e.g., PRO for "promoter"), 3) a short description of the part, 4) its DNA sequence

Column headers should not be present.
