Hi Ravikumar, next nightly build of Phenix (dev-4661 and up, likely becomes available tomorrow) found in the usual place
https://phenix-online.org/download/nightly_builds.cgi?show_all=1 will contain the new command line program called phenix.map_values_along_line. The program inputs the map (real-space map in mrc format) and Cartesian coordinates of two points in space, and it outputs map values along the line connecting these two points. Example: phenix.map_values_along_line map.mrc point_1="1.123 2.455 3.765" point_2="4321 5.567 6.987" Optionally, you can specify the step that map values are computed at going from one point to another, by default it is set to 0.01 (use step parameter for this). Map values are calculated using tricubic interpolation. Optionally you can choose a less accurate eight-point interpolation (use interpolation keyword for this). Those interested in CCTBX implementation of underlying functionality of this program grep for 'map_values_along_line_connecting_two_points' that will find you the function and the test that exemplifies the use of this function. Hope this solves your problem, Ravikumar.
