History

  • 10-03-03 ? first version released

Source

Released under the GNU General Public License.

Requires

ImageJ ver 1.43o or higher (ImageJ, upgrade page).

Installation

Download K_kymoquant.ijm to a place where you can access easily. Install the macro by [Plugins→Macros→Install…].

Description

Measures orientation of kymograph by estimating the direction of image texture. Outputs movement velocity in pixels / frame.

(more explanation on measurement principle is planned here)

Tip: When kymograph traces are steep, analysis results become unstable since calculation of direction involves tanθ. Be sure to capture original sequence with high time resolution if possible.

Work Flow

Kymograph should be prepared by your self either by manually using stack reslicing function in ImageJ, or ImageJ Kymograph plugin.

If you want to measure full frame of the kymograph, simply apply [Plugins → Macros → Measure Velocity from Kymograph: Full Frame].

If you want to measure only part of the kymograph, then select a area by rectangular ROI tool and then [Plugins → Macros → Measure Velocity from Kymograph: ROI].

[Plugins → Macros → Scan Kymograph and Measure - Automatic Multiple Measurements] will automatically divide the kymograph into segments and sequentially measure the kymograph along the time line.
