The MFID program is used to simulate an NMR spectrum. The output file can be Fourier transformed using the MFFT program.
The MFID program is called as follows:
<Machine ID>mfid
All parameters to the program are read from standard input, possible redirected to a file.
The following is a list of all commands accepted by the MFID program. Processing starts when all commands have been read. All commands must be given in upper-case.
Format:
DATAFILE <name> <expno> <procno> <disk> <user>
Description:
Defines the name of the file to be created.
Format:
DIMENSION <dim>
Description:
Defines the number of dimensions in the output file.
Format:
SIZE <dim> <size>
Description:
Defines the number of data points in dimension dim to size. Note, for dimension zero, size is the number of complex points, for higher dimensions size is the number of real points.
Format:
PPM <dim> <hz> <ppm>
Description:
Defines the ppm axis in dimension dim: The frequency of hz Hz is set to ppm ppm.
Format:
PEAKFILE <filename>
Description:
Reads filename to get the list of peaks to simulate in the spectrum.
The file contains one line for each desired peak in the spectrum. Each line is formatted as follows:
<intensity> <ppm_0> <ppm_1> <ppm...> <t2_0> <t2_1> <t2_...>
where intensity is the desired height of the peak, the ppm values (specified in ppm) define the center of the peak, and the t2 values (specified in seconds) define the linewidth.
For an n-D spectrum, each line must contain 2n+1 numbers.
Format:
SWEEP <dim> <width>
Description:
Set the sweep width in dimension dim to width Hz.
Format:
FREQUENCY <dim> <sf>
Description:
Sets the spectrometer frequency in dimension dim to sf MHz.
Format:
NOISE <level>
Description:
Adds a noise of max intensity of level.
