Appendix - setting different search parameters

Search performed in the MS Search program may follow dozens of different settings. Clarity software does not directly offer all of these settings, but some may be forced to Clarity searches using configuration file.

In MS Search, these search parameters are available through Options - Library Search Options command. Using the configuration file, only two settings can be changed from Clarity software - Spectrum Search Type and Presearch. When nothing is entered in the configuration file, the used parameters in Clarity are :

• Spectrum Search Type - Identity, Quick
• Presearch - Off

To change the values, locate the others.ini file in /CFG/ subdirectory of Clarity installation directory (C:/CLARITY by default) and open it in a text editor (e.g. Notepad). Create a new section for MS parameters looking as below:

[MS]
SearchMode=Q
Presearch=Default
 

The available values for parameters are:

• Spectrum Search Type - key SearchMode , available values I (meaning Identity, Normal) or Q (meaning Identity, Quick)
• Presearch - key Presearch, available values Default or Off

In future versions, new configurable values or parameters may be added.
