Printing Data - Velocity or Equilibrium Data:

Once you have edited experimental data with the editing module, you can print the edited experimental data to a postscript printer or file. More information about using the UltraScan printer control functions can be found here.

To print data, click on "Print Data" from the File Menu on the UltraScan Main Menu. You can select from velocity and equilibrium experiments. The program will display the the Print Data window for either velocity or equilibrium data.

Run Control Functions:

  • Load Data: Load edited data sets (with the *.us.v or *.us.e suffix). A file dialogue will allow you to select a previously edited velocity or equilibrium experiment. If you selected "Velocity", only previously edited velocity experiments will be shown, and the same for equilibrium runs. Once a run has been selected, the Run Details will be shown. Click on the "Accept" or "Cancel" button, and the program will display the first available dataset for this run in its entirety. If the data was edited with an older version of UltraScan than the current, an error message will be displayed.
  • Run Details: View the diagnostic details for a velocity or equilibrium experiment.
  • Print Data: This function allows you to print the data to a postscript printer or postscript file. Before printing, you may wish to use the various controls to customize the appearance of the printed data (see below).
  • Reset: Reset all display parameters to their default values.
  • Help: This help file
  • Close: Exit this module

Run Information:


  • Run ID: The name of the run given during editing
  • Temperature: The average temperature calculated from the entire run
  • Available Cells: The numbers the cells that contain analyzable data
Clicking on a cell and wavelength selection will bring up the cell contents description for that cell and wavelength. Scroll through this list to bring up information for cells > 3. If there is no data available for the selected cell, the program will list "No Data available". Selecting a cell/wavelength combination will automatically bring up the corresponding dataset and present the analysis. For equilibrium scans, you can also select the channels (for runs containing multi-channel centerpieces)

Changing Display Parameters:

  • Data Smoothing: Use this feature to smooth the experimental data. For noisy data, increasing this parameter can improve the clarity and appearance of the results considerably. Please note: Whenever possible, especially for very steep boundaries with low diffusion, try to avoid using too much smoothing to prevent artificial modification of the boundary shape. Smoothing is performed based on a frame average. The number shown represents the size of the smoothing kernel used (the number of datapoints averaged for a single point). The algorithm used is non-destructive of the original data and hence the smoothing is reversible. Also, point smoothing is independent, where the smoothing of one point does not have any effect on the smoothing of its neighbors. Only unsmoothened points are used for the calculation of the smoothed value. Each time you click on the counter, the current dataset will be reset to the full dataset.
  • % of Boundary: This is the portion of the boundary used for the analysis. 100 % refers to the entire boundary, reaching from the baseline concentration value to the plateau concentration value. This portion is shown in yellow in the experimental data plot. Excluded data is shown in blue. Changing this number will automatically reset the position of the analyzable portion of the boundary in the center of concentration between the baseline and the plateau concentration.
  • Boundary Position (%): For percent-boundary values less than 100 %, this number refers to the percentage of total concentration by which the remainder (=un-analyzed portion of the boundary) is shifted away from the baseline. A value of 0% refers to a data analysis start at the baseline. This number is always less than or equal to 100 % - (% of Boundary). It allows you to control the position of the analyzed portion relative to the baseline. The blue colored portion of a scan is excluded from the analysis, and the yellow portion is analyzed.
  • Exlude Single Scan: When setting this counter to a non-zero value, the respective scan will be highlighted in red. Clicking on "Excl. Single Scan" while a scan is highlighted in red will delete this scan from the analysis. Deleting scans from the analysis is irreversible and can only be reset by clicking on the "Reset" button or by reloading the data (when smoothing, the data is always automatically reloaded, causing the number of scans to be reset to the original count).
  • Exclude Scan Range: Same as "Exclude Single Scan", except for multiple scans. To use this feature, select first the start scan of the range by using "Exclude Single Scan", then complete the scan range by using "Exclude Scan Range".
