Re-ordering Scan File Sequences:

The Scanfile Re-ordering Utility can be loaded from the Utility Menu in the Main Menu section of UltraScan. The reordering of scan files program allows you to fix corrupted archives of raw data files acquired with the Beckman Data Acquisition software. On occasion, file collection fails for a file in the sequence or one or more files end up missing for various reasons, creating "holes" in the sequence. The UltraScan software expects all files to be in proper sequence, and this utility allows you to reorganize a Beckman Data Acquisition data directory such that all files are in the proper sequence expected by UltraScan.

Explanation for fields and buttons:

Absorbance Data/Interference Data:
select the type of data to be re-ordered. Depending on the optical system selection, the file suffixes differ (interference = *.ip* and absorbance = *.ra*) and need to be dealt with separately.

Select Directory:
Select a directory containing the corrupted data. All scan files to be reordered need to be located in the same sub-directory. After selection of the directory, the selected directory will be displayed in the directory panel and all files residing in the selected directory will be checked for contents and sequence. As soon as the file check has completed, all fields will be updated with the corresponding values for the files in the selected directory. The default cell to be displayed will be the first cell in the sequence that contains data. See "Cell selection box" for more information on how to display information for a particular cell.

Help:
This Help file.

Total Cells:
The number of cells contained in this run. It is expected that each directory only contains a single run, i.e., all cells and scanfiles located in a selected directory have to belong to the same experiment.

Status:
Displays the status of various file operations, such as file checking and sorting.

Cell selection box:
When the data directory is selected, all possible cell positions (1-8) are examined for the presence of data. If data are found in a particular cell, it will be displayed with "Cell x contains data", otherwise, it will be listed as "Cell x is empty". Clicking on the desired cell will update all fields with the corresponding information for this cell.

Message Box:
The Message Box provides instructions to user about the steps required to order cells as well as information about the status of the program and properties of a selected cell.

Cell contents:
This panel will show the contents of the selected cell as entered in the Beckman Data Acquisition software.

Check Wavelength(s):
Clicking on this button will check for the presence of multiple wavelengths (disabled for interference data) in the selected cell. All wavelengths that have been used to collect data in this cell will be listed here.
Note: If the cell contains data collected at multiple wavelengths, this program is not useful, unless the wavelengths are very close together and were not selected to be different, but resulted from inaccurate positioning of the diffraction grating. If absorbance data for different wavelengths were collected, the message window will display the following message:

This cell contains data which was measured at multiple wavelengths! It is not safe to re-order this cell!

If all scans were measured at the same wavelength, the following message will be displayed:
For in-sequence scans:
All scanfiles of this run are in the proper sequence. No reordering is necessary.

For out-of-sequence scans:
This cell was measured at a single wavelength. It is safe to re-order this cell.

Wavelengths:
After clicking on "Check Wavelength(s)", all wavelengths used to measure the selected cell are displayed here.

Order this Cell:
Re-order the scan file sequence for the selected cell.

Order all Cells:
Order the scan file sequence for all cells. The program will not check automatically if the cell was acquired at different wavelengths. The user has to do that manually.

Total Scans:
The number of total scan files found for the selected cell is displayed here.

First Scanfile:
The first scanfile found for the selected cell is shown here. If the filename doesn't display 00001. here, scan files are missing in the beginning of the run.

Last Scanfile:
The last file containing data found for the selected cell. If the number of the prefix in the scan file name does not agree with the number shown in total scans, the run contains out-of-sequence scan files and should be reordered.
