The simplest form of a "calculation", is the value export. Data can
be modified before value extraction using filters, intervals, sensor
groups, normalization, differentiation or a scaling factor. Each of
these transformations corresponds to a separate page on the value
export sheet and is exlained in more detail below.
Value export can either be done from ERP/ERF data files listed in
the batch docking window, or from "peripheral-physiology" data in a
MySQL database. This choice must be made on the "data in"-page of the
value export sheet of the calculate dialog ( see below).
==> Please note that currently, only export of ERP/ERF data from
datafiles "in the batch" is implemented.
Values are written to a standard textfile by default. For ERP/ERF
data, you can alternatively choose to overwrite the files in the
batch, save renamed copies with the modified values next to the
original files, or save files in a specific folder using different file
formats. The last option ("statistics export") is used only when the
exported values are sent directly for factorial analysis in R, and
cannot be selected manually.
