Utilities:

These functions provide access to various utility modules of UltraScan.

1. System Utilities
   The UltraScan system utilities allow you to access system resource information if you run Ultrascan on a Linux computer. An explanation of the various modules can be found here.

2. Archive Manager
   The archive manager allows you to combine many related files from an analytical ultracentrifugation experiment into a single compressed archive file and manage these archives. Additional information about the archive manager can be found here.

3. Re-order Scanfile Sequence
   The scanfile re-ordering utility allows you to correct file sequences in case of missing or corrupted files or holes in the sequence. UltraScan requires that all experimental data files are in sequence. More information about this analysis can be found here.

4. Merge Scanfiles from 2 Directories
   If an experiment was interrupted by a technical problem or you had to restart data collection on the same experiment, you can combine the data from the two resulting directories in a single directory with this utility

5. Edit Cell ID (Velocity)
   The cell descriptions of edited data can be modified after editing is completed by selecting "Edit Cell ID's". More information on this option can be found here. This function will edit the cell description for a velocity experiment.

6. Edit Cell ID (Equilibrium)
   The cell descriptions of edited data can be modified after editing is completed by selecting "Edit Cell ID's". More information on this option can be found here. This function will edit the cell description for an equilibrium experiment.

7. Copy Velocity Run
   This utility allows you to make a copy of the edited data from a velocity experiment. On occasion you may want to generate results using different analysis approaches on the same dataset and compare the results. More information on this option can be found here.

8. Copy Equilibrium Run
   This utility allows you to make a copy of the edited data from a velocity experiment. On occasion you may want to generate results using different analysis approaches on the same dataset and compare the results. More information on this option can be found here.

9. Combine G/g(s) Distribution Plots (vHW)
   This function allows you to combine van Holde - Weischet integral ori differential distribution plots from different cells in a single plot. Details about this module are described here.

10. Combine G/g(MW) Molecular Weight Distributions (vHW)
    This function allows you to generate molecular weight distributions from S20,W-corrected van Holde - Weischet integral or differential distributions. The distributions can be combined from different cells and runs in a single plot. Details about this module are described here.

11. Combine C(s) Distributions
    This function allows you to generate s-value distributions from the 2-dimensional spectrum analysis or the C(s) method. An explanation of this module can be found here.

12. Combine C(MW) Distributions
    This function allows you to generate molecular weight distributions from the 2-dimensional spectrum analysis or the C(s) method. An explanation of this module can be found here.

13. Combine C(D) Distributions
    This function allows you to generate diffusion coefficient distributions from the 2-dimensional spectrum analysis or the C(s) method. An explanation of this module can be found here.

14. Scan Diagnostics
    Use this function to present the contents of a scanfile in a graphical way, and list all parameters, such as time, wavelength, temperature, omega-square-t integral, etc. More information can be found here.

15. Calculate DNA/RNA MW
    This module allows you to load nucleic acid files from the harddrive or the database and calculate molecular weights. More information about this function can be found here.

16. Buffer Corrections
    Sedimentation experiments need to be corrected for standard conditions at 20^oC and water. This utility allows you to create and import buffer definitions and correct for buffer conditions based on individual buffer components. Buffer definitions can be saved and loaded from disk or database. More information on this function is available here.

17. Calculate Protein MW and vbar
    This function allows you to import peptide sequence files to calculate the molecular weight, partial specific volume (vbar), and extinction coefficient at 280 nm of the peptide. More information can be found here.

18. Global Extinction Fit
    With the "Global Extinction Fit" function you can generate extinction profiles from wavelength scans. Multiple wavelength scans are simultaneously fitted to a global model describing the extinction variation with wavelength. More information about this analysis can be found here.
