## Function Documentation

## ◆ pmsco_load_xyz()

string pmsco_load_xyz | ( | string | pathname,
|  | string | filename
| ) |  |

load an xyz cluster file

load an xyz cluster file into the current data folder the wave names are at (atom types), xx, yy, and zz. at is a text wave containing chemical symbols. existing waves are overwritten.

Parameters

  pathname | name of igor symbolic path. can be empty (path is taken from filename argument).
  filename | file system path. can be empty (will open dialog).

## ◆ pmsco_save_scan()

string pmsco_save_scan | ( | string | pathname,
|  | string | filename,
|  | string | energy,
|  | string | theta,
|  | string | phi,
|  | string | alpha,
|  | string | intensity,
|  | string | sigma,
|  | dfref | sdfr = `defaultValue`
| ) |  |

save waves in a PMSCO scan data file.

Warning
  experimental. this function is work in progress.

cases

- phd scan: separate energy, theta, phi, alpha, intensity waves
- hemi scan: separate energy, theta, phi, intensity waves
- polar/azi scan: intensity wave, angle is in x scale

options

- sigma wave

the data arguments are strings and can be

- the name of an existing wave (optionally including a path relative to the specified source folder),
- the string representation of a constant numeric value,
- a dimension specifier ("x", "y", "z" or "t") referring to the dimension scale of the intensity wave, or
- an empty string if the corresponding axis should not be saved.

wave names can include a path relative to the specified source data folder. by default, the function looks in the folder specified by the sdfr argument.

Parameters

  pathname | name of igor symbolic path to destination folder. prompt user if empty.
  filename | requested file name. prompt user if empty.

Note
  the extension should include the symbols of the included parameters in the order "etpais". if the intensity wave contains a modulation function, ".modf" should be inserted before the extension. in interactive mode, igor tends to override the file extension with a standard one like ".txt".

Parameters

  energy | energy specification. see description above.
  theta | theta specification. see description above.
  phi | phi specification. see description above.
  alpha | alpha specification. see description above.
  intensity | name of intensity (or modulation) wave. this parameter is mandatory and must refer to an existing wave.
  sigma | sigma specification. see description above.
  sdfr | source data folder reference. default: current data folder.

Returns
  file name

## ◆ save_scan_helper()

static string save_scan_helper | ( | string | destname,
|  | string | value,
|  | wave | template,
|  | dfref | destdfr,
|  | string | wavenames
| ) |  |
| static
