# 18.6.1 The Deconvolution Dialog box

This tool is only accessible from script:

1. Make a workbook or a graph active.
2. Open the Command Window or Script Window and run the following LabTalk script to access the deconv X-Function:
deconv -d
Dialog Theme See Dialog Themes.
Recalculate Specifies the signal (a known convolution result). See Specifying Your Input Data. Specifies the response. See Specifying Your Input Data. Specifies the sampling interval. The default is , which corresponds to an automatically computed interval. Specifies the deconvolution options. Normalize Response: Specifies whether the response should be normalized to [0, 1], before it is used to calculate the deconvoluted signal. Wrap Response: Specifies whether the response should be wrapped, before it is used in the deconvolution calculation. If this is selected, the maximum data point in the original response will become the first data point in the wrapped response. Deconvolution Type Specifies whether the deconvolution is circular or linear. This will decide how the data points outside the input range will be treated. Linear: Data points outside the input range will be viewed as zeros. Circular: Data points outside the input range will be viewed as repetition of the data points within the range. Specifies the output. See Output Results.
