How to Troubleshoot Common Gating Errors in Cyflogic Cyflogic is a powerful software tool for analyzing flow cytometry data. However, drawing and applying gates can sometimes lead to unexpected results or errors. This guide will help you quickly identify and resolve the most common gating issues in Cyflogic. 1. Missing Data Points Inside the Gate
Sometimes you draw a gate around a population, but the software registers zero events inside it.
Check the Axis Scaling: Ensure your plot is not set to an aggressive log scale that pushes data points off the visible grid.
Verify Parameter Names: Confirm that the X and Y axes match the parameters used when the gate was originally created.
Refresh the Plot: Click a different sample and return to the current one to force Cyflogic to recalculate the event count. 2. Polygon Gates Not Closing
When drawing a manual polygon gate, the gate might stretch across the screen instead of completing.
Double-Click to Close: Cyflogic requires a double-click to connect the final vertex to the starting point.
Avoid Overlapping Points: Do not click too close to the very first point, as this can confuse the click detection.
Press Escape: If the gate is stuck, press Esc to cancel the drawing action and start fresh. 3. Gates Not Applying to All Samples
You created a master gating strategy on one sample, but it is not appearing on subsequent files in your workspace.
Set Hierarchy Properly: Ensure your gates are nested correctly in the workspace tree view.
Apply to Group: Right-click the gate in the workspace window and select “Apply to All Samples” or drag it to the top-level group folder.
Check File Formats: Mixing FCS 2.0 and FCS 3.0 files in the same workspace can cause automated gating layout errors. 4. Distorted Gate Shapes After Loading Workspaces
Saved workspaces can occasionally load with shifted, shrunk, or warped gates.
Match Resolution Settings: This happens when the original data was analyzed on a monitor with a different screen resolution or aspect ratio.
Recalibrate the Plots: Manually click and nudge one vertex of the distorted gate to force Cyflogic to snap the shape back to its proper coordinates.
Update Cyflogic: Ensure you are running the most stable version of the software, as older builds have known workspace scaling bugs. To help tailor this guide, let me know:
Which specific error message or behavior are you currently seeing?
What version of FCS files (e.g., FCS 2.0, 3.0, 3.1) are you importing? Are you using polygon, quadrant, or interval gates?
