.TH CELL_EXPLORER 1
.SH NAME
cell_explorer \- Unit Cell Explorer
.SH SYNOPSIS
.PP
.B cell_explorer \fIindexing-results.stream\fR
.SH DESCRIPTION
The Unit Cell Explorer allows you to visualise the distribuftions of unit cell parameters resulting from processing a series of diffraction patterns with \fBindexamajig\fR.
.P
Start the Cell Explorer simply by executing \fBcell_explorer\fR followed by the filename of the stream which contains your indexing results.
.P
The Cell Explorer window shows histograms for, left to right respectively, a, b and c in the top row and alpha, beta and gamma on the bottom row.
.P
Click and drag to move the graphs to the left and right. Scroll up and down to zoom in and out. Press plus or minus to increase or decrease the number of bins used to calculate the histogram. Changing the binning is usually necessary when zooming in or out by a large amount.
.P
Different colours are used to represent different centering types (P, A, B, C, I, F, H and R) according to the colour key at the top right. Click one of the squares in the key to change the colour used for that centering type to grey, and again to change it to black.
.P
Click and drag with shift held down to select a range of values in one of the histograms. Unit cells which have that parameter outside the selected range will be shown in grey in all the histograms.
.P
After selecting a range of values, use Tools->Fit Cell (or press Ctrl+F) to fit a normal distribution to the histogram data. The mean and standard deviation of the parameter will be shown. Unit cells will not be included in the fit if they are outside the ranges selected for the other parameters.
.P
The indexing algorithms found in the stream are shown as buttons at the top. Click one of the buttons to deselect it, and again to select it again. Unit cells from deselected algorithms will not be shown in the histograms (not even in grey).
