AdjustVolume

adjust_volume_grey_levels

Purpose

This utility searches for a linear transformation of the gray values of a volume so that the error between the theoretically projected images and the experimental images is minimized. This program must be used before computing the Volumetric SSNR if the reconstruction algorithm scales the output volume differently.

Usage

$ adjust_volume_grey_levels -i [Xmipp volume] -sel [selfile] ...

Parameters

• `` Volume to adjust the range
• `` Set of projections of this volume
• `` Output adjusted volume. By default, the input one
• `` Optimize the linear transformation. By default, keep the initially computed
• -probb_eval [p0.2] = The goal function is evaluated each time from a random set of projections. Each image has a probability p of being evaluated

Examples an notes

Adjust a volume to a set of images

$ adjust_volume_grey_levels -i input_volume.vol -o output_volume.vol -sel experimental.sel
