Radius from Chord- This computes the radius of a circle based on the length of a chord and the chord's center height. Radius from Area - This computes the radius of a circle given the area. Circumference from Area - This computes the circumference of a circle given the area. Radius from Circumference - This computes the radius of a circle given the circumference. Circle around a Triangle - This computes the radius of a circle that circumscribes a triangle given the length of the three sides ( a,b,c) of the triangle. Circle within a Triangle - This computes the radius of a circle inscribed within a triangle given the length of the three sides ( a,b,c) of the triangle. Arc Lengths - This computes the length of a cord segment (arc length) on a circle given the radius (r) and angle ( Θ). Circumference - This computes the circumference of a circle given the radius ( C = 2 π r). Radius - Center to a Point - This computes the radius of a circle given the center point ( h,k) and any other point ( x,y) on the circle. Area of Annulus- This computes the area of an annulus (ring) given the inner radius ( r) and outer radius ( R). Sector Area f(r,Θ)- This computes the area of a sector (pie slice) of a circle given the radius ( r) and angle ( Θ). Segment Area f(r,h) - This computes the area of an arc segment of a circle given radius ( r) and the depth ( h) into the circle. Segment Area f(r,θ) - This computes the area of an arc segment of a circle given the radius ( r) and angle ( θ). Circle Area - This computes the area of a circle given the radius (A = π r 2). The length of the chord (d) is the distance between two points on a circle. The formula for the length of a chord is: However, this can be automatically converted to other length units via the pull-down menu. INSTRUCTIONS: Choose units and enter the following:Ĭhord of a Circle (d): The calculator compute the length of the chord ( d) in meters. (Initially a segment of a circle, but generalized to a particular segment along some given curve.) The arc length is the length. An arc is a segment of a curve between two points. 
(Usually of a circle, but I suppose that use can be and has been generalized.) Chord length is, therefore, the straight line distance between two points on the curve.

The results will be stored in a folder named “output_directory”.Ĭlick here to download the script to load images from PMA.The Chord of a Circle calculator computes the length of a chord ( d) on a circle based on the radius ( r) of the circle and the length of the arc ( a). A chord is a straight line joining two points. This will start CellProfiler in headless mode and execute “my_pipe_line.cppipe” against the image we fetched.
Next we invoke CellProfiler, provided that we have our pipeline ready, in the following manner: CellProfiler.exe -c -r -data-file input.csv -o /output_directory -p my_pipe_line.cppipe It will also create a CSV file named input.csv, again in the current directory. This will fetch a snapshot of the image and save it as slide1.jpg in the current directory. A simple case for an RGB image is to print the path to the image file inside the CSV.įor example if we want to feed the image at c:slidesslide1.svs to CellProfiler, we first fetch a snapshot using the attached Python program by issuing: python CellProfiler.py c: /slides/slide1.svs To achieve this, first we have to download an image from PMA.start and create an accompanying CSV file for it that contains required meta data.

In addition to the first example, where we displayed how to fetch a snapshot of an image from PMA.start using Python, we can extend the example slightly so that we can feed the snapshot image to CellProfiler for further analysis.ĬellProfiler can be invoked by the command line and instructed to execute a pipeline against a particular image. CellProfiler can be retrieved from its own website.
