Step-by-Step GeneDoc Tutorial: From Import to Publication-Ready Figures

GeneDoc is a lightweight tool for viewing, editing, and annotating multiple sequence alignments. This tutorial walks through a typical workflow: importing alignments, adjusting display and shading, annotating features, exporting high-quality images, and tips for producing publication-ready figures. Assumed: you have a multiple sequence alignment file (FASTA, CLUSTAL, or similar) produced by an aligner (e.g., Clustal Omega, MUSCLE).

1. Prepare your alignment

  1. Generate alignment: Run your preferred aligner (Clustal Omega, MUSCLE) on the raw sequences and save the output in a compatible format (FASTA aligned, CLUSTAL .aln).
  2. Check sequence names: Keep names concise (≤30 characters) to avoid crowded labels in figures.
  3. Clean up gaps: If necessary, edit the alignment in the aligner or a sequence editor to remove obvious misalignments or long terminal gaps.

2. Import the alignment into GeneDoc

  1. Open GeneDoc.
  2. Choose File → Open and select your alignment file. GeneDoc recognizes CLUSTAL and other common alignment formats; if your format isn’t recognized, save/export from your aligner as CLUSTAL or aligned FASTA.
  3. Confirm sequence order and labeling; use Edit → Sequence Order if you need reordering.

3. Configure the view

  1. Font and spacing: From the Display menu, set a monospaced font and appropriate size so residues are clearly visible.
  2. Wrap length: Set columns per line (e.g., 60 or 80) to balance readability and figure width.
  3. Consensus display: Enable consensus lines if you want to show conservation summaries beneath sequences.

4. Apply shading and coloring

  1. Open the Shading/Color dialog (Format → Shading).
  2. Choose a shading scheme: Use identity shading (highlights residues identical to a reference) or property-based coloring (hydrophobic, polar, charged).
  3. Adjust thresholds: Set identity/conservation thresholds to control how strict shading is (e.g., 70% identity).
  4. Preview and tweak: Inspect shaded columns and adjust color contrast so colors reproduce well in print and grayscale. For publication, prefer high-contrast palettes and avoid red/green-only distinctions.

5. Annotate features and labels

  1. Add sequence annotations: Use the Annotation or Comment tools to mark domains, motifs, active sites, or post-translational modifications. Place short labels above or below the alignment.
  2. Numbering scheme: Confirm sequence numbering matches the biological reference (choose alignment numbering or original sequence coordinates).
  3. Arrows/boxes: Draw boxes or lines to emphasize conserved regions or structural features using the drawing tools.

6. Create inset or zoomed regions

  1. For long alignments, choose a conserved segment to display as an inset.
  2. Use the Select tool to crop the region and copy it into a new GeneDoc window or export separately for a detailed panel.

7. Final layout for figures

  1. Remove unnecessary elements: Turn off gridlines or background that may clutter the figure.
  2. Add scale bars and labels: Include sequence position scales and descriptive figure captions outside GeneDoc in your figure editor.
  3. Assemble multipanel figures: Export multiple panels (full alignment, zoomed view, annotation schematic) and combine in a graphics program (Inkscape, Illustrator).

8. Export high-quality images

  1. Use File → Export to save as BMP or EMF if supported; EMF preserves vector-like quality on Windows. If you need raster images, export at a high resolution (e.g., 300–600 dpi).
  2. If GeneDoc’s export options are limited, take a full-screen, high-resolution screenshot and crop in an image editor, or copy/paste into Illustrator/PowerPoint and save as PDF or EPS.
  3. For grayscale journals, convert a color export to grayscale and verify contrast of shaded regions.

9. Check journal requirements

  1. Confirm figure size, resolution (usually ≥300 dpi), and file format (TIFF, EPS, PDF) required by your target journal.
  2. Ensure fonts and labels remain legible at final print size; increase font sizes in GeneDoc before export if necessary.

10. Final polishing tips

  • Legend: Provide a clear legend explaining shading/colour rules and numbering.
  • Accessibility: Avoid color combinations that are inaccessible to colorblind readers; use patterns or labels in addition to color when needed.
  • File backups: Save a GeneDoc project file and export intermediate files so you can revise figures quickly.

Conclusion Follow this workflow to turn raw alignments into clear, annotated, publication-ready figures using GeneDoc: prepare and import the alignment, optimize display and shading, annotate key features, export at high resolution, and assemble final panels according to journal specifications.
