This is the Bright Search Interface (QSI) that allows to use Geena 2 with some flexibility.

You may be interested in using the Quick Search Interface (QSI), which adopts default values for the majorityy of parameters, or the Standard Search Interface (SSI), by which you are able to tune all available parameters to your needs.

Using Geena 2 should be straightforward. Input and output data use a simple format. Nevertheless, should you have any problem, see the help or the information on data formats pages.

NB! This version includes a new feature. When a normalization peak is provided, it is used to calibrate m/z values.
In practice, for each spectrum all m/z values are recomputed by taking into account the difference between the teorethical and the actual m/z values of the normalization peak.

NB! Move your mouse over the icon for a contextual help.
