# Exporting Data

Clicking the data export button in the simulation output panel will bring up the data export configuration window shown below.

The data export configuration window is similar in functionality to the plotting configuration window presented in the Plotting Time Series Data section. It consists of two tabs, one for time series output and one for histogram output. First we will consider the former. At the top of the window is a drop-down box for choosing the simulation output to export.

Below the output selection are two rows of radio buttons. In the first row one selects whether to plot species populations, cumulative reaction counts, binned reaction counts, or all reaction events. For a given output type, not all of these categories are relevent. For example one may export the reaction events only if all reaction events were recorded during the simulation. In the second row of radio buttons one selects whether to plot trajectories or statistics. For the latter the mean and optionally the standard deviation of the trajectory curves are plotted.

Next is a grid which lists either the species or reactions in the column headers. Here one may select the items to export. If one is exporting statistics one may choose which means, and optionally which standard deviations, to export. Clicking on a grid cell will toggle the state. Left/right clicking on a column header will select/deselect all of the items.

At the bottom of the data export configuration window one may select the delimiter for data fields in a row. Choosing a comma will result in a CSV file (comma-separated values) with a default file extension of `.csv`. Choosing either a space or tab will result in a text file with a default file extension of `.txt`. Any of these file formats may be imported into spreadsheet programs like Calc, Numbers, or Excel.

For the histogram data tab there are no radio buttons for selecting the data type to export. All of the histograms for the selected species are written. This tab of the data export configuration window is shown below.
