Extract unique sequence IDs from alignment files.

Steps

Section titled “Steps”
  1. Select Sequences in the navigation bar A.
  2. Open Extract and map sequence IDs from the tool picker B: the tool list on wide windows, or the tool name at the top of the page on phones.
  3. Add the input files C with Browse files, Browse folder, or Open archive. SEGUI searches a folder and its subfolders for files that match the tool's input format. See file input for mobile options.
  4. Select Browse under Select output directory to choose the output folder. On phones and tablets, enter a Directory name instead; SEGUI saves it in the app's own folder.
  5. Add prefix for the output files.
  6. Turn on Map sequence ID to map the IDs across files (optional). See Sequence ID Mapping for more details.
  7. Select the run button D, labeled Extract ID, to start the task.

Output

Section titled “Output”

The app will generate a file containing the list of unique sequence IDs in your dataset. The default name is the prefix input.
