Geena 2 Build August 31, 2021.

This system is under active development, please forgive us for possible errors and send us your comments, criticisms and congratulations, if any.

Welcome to Geena 2, a tool for MS spectra filtering, averaging and aligning. (Bright Search Interface)  Job information   Job name:   Data file: (see information on data file format and an example file)   Analysis range: From m/z to m/z Normalization peak: No    Yes, at m/z   Minimum number of signals in average spectra: Only signals present in all spectra Signals present in all spectra but one Signals present in the majority of spectra (> 50%) All signals present in at least two spectra All signals, even when present in one spectra only Signals present in at least the given number of spectra Specify: Minimum number of signals in aligned spectrum: Only signals present in all spectra Signals present in all spectra but one Signals present in the majority of spectra (> 50%) All signals present in at least two spectra All signals, even when present in one spectra only Signals present in at least the given number of spectra Specify:   Your email: Country:   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!
