extposition(1) General Commands Manual extposition(1) NAME extposition - get list of position numbers for axoneme doublets SYNOPSIS extposition DESCRIPTION This program produces a list of position numbers for portions of images extracted by the program Extstack. It is a quick hack of that program. It requires the two point files used by Extstack, the reference point file and the extraction point file. In addition, it requires a file of points specifying the location of position 1 on whichever sections that can be determined. Also, one must specify whether position numbers increase in the counter-clockwise or clockwise direction. If there is a position 1 point for a particular section, then the pro- gram assigns appropriate position numbers to all of the extraction points on that section; otherwise it assigns a position number of zero.
