Boulder Laboratory for 3-Dimensional Electron Microscopy of Cells EXTPOSITION(1) 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 program assigns appropriate position numbers to all of the extraction points on that section; otherwise it assigns a position number of zero.
