# Data processing commands

Commands to setup the data processing (mainly MYTHEN related)

- flatfield [fn] `put` sets flatfield file to `fn` (relative to `ffdir`). returns the flatfield file name relative to `ffdir` (string). If

- ffdir [d] Sets/gets the directory in which the flat field file is located. `Returns` ``(string) ffdir

- ratecorr [ns] Returns the dead time used for rate correections in ns (int). `put` sets the deadtime correction constant in ns, -1 will set it to default tau of settings (0 unset). `Returns` ``(double with 9 decimal digit precision)

- badchannels [fn] `put` sets the badchannels file to `fn` . returns the bad channels file name. If

- angconv [fn] `put` sets the angular conversion file to `fn` . returns the angular conversion file name. If

- globaloff [f] Sets/gets the beamline angular global offset (float).

- fineoff [f] Sets/gets the angular fine offset of the measurement (float).

- binsize [f] Sets/gets the bin size used for the angular conversion (float).

- angdir [i] Sets/gets the angular direction. 1 means increasing channels number as increasing angle, -1 increasing channel number decreasing angle.

- moveflag [i] Sets/gets the flag for physically moving the detector during the acquisition of several positions. 1 sets (moves), 0 unsets.

- samplex [f] Sets/gets the sample displacement in th direction parallel to the beam in um. Unused!

- sampley [f] Sets/gets the sample displacement in th direction orthogonal to the beam in um. Unused!

- threaded [i] Sets/gets the data processing threaded flag. 1 is threaded, 0 unthreaded.

- darkimage fn Loads the dark image to the detector from file fn (pedestal image). Cannot get.

- gainimage fn Loads the gain image to the detector from file fn (gain map for translation into number of photons of an analog detector). Cannot get.
