Defining New Cell Types:
The cell geometry types are defined in a text file, "channels.txt", that gets installed in the HeteroAnalysis application directory (typically "C:\Program Files\HeteroAnalysis\"). The contents of the file which gets installed with the program is shown below (line numbers are shown for the purpose of describing the file).
"channels.txt"
1) 2
2) 1, 2
3) Standard parallel-walled cell
4) 5.8, 0.200
5) 7.2, 0.200
6) 2, 2
7) Standard 2.5 degree sector-shaped cell
8) 5.79, 0.252636
9) 7.21, 0.314596
Line 1: number of cell types defined in the file
Line 2: Type#, number of data points
Line 3: cell type description
Line 4: radius(1), channel width(1)
Line 5: radius(2), channel width(2)
Line 6: Type#, number of data points
Line 7: cell type description
Line 8: radius(1), channel width(1)
Line 9: radius(2), channel width(2)
The data points should be entered as comma-separated values in units of centimeters. In the case of the standard parallel-walled cell it is not necessary for the channel width to be accurate but in all other cases the cell dimensions should contain accurate values for the width. The two standard channel types shown here each only require two points to completely define their geometries. It is probable that other geometries will require a larger number of points to completely define the channnel(s).
