Blob Detection on SIC (or CLIC)

Hi, may I perform blob detection on the SIC (or CLIC) to take advantage of the mass selectivity offered by high-resolution mass spectrometers? Thanks!

Re: Kendrick mass defect (KMD) analysis

Hi,

I created the polygon and selected the 'include' checkbox. How do I use the 'Area Spectrum' feature?

Kendrick mass defect (KMD) analysis

Dear All: The kendrick mass defect (KMD) analysis is performed for the mass peaks of the active spectrum only? Users' Guide: "The table, on the right, shows the exact mass, mass defect, and intensity for each peak." In petroleomics, we typically use the KMD analysis for all molecular ions ...

Q Exactive GCxGC data

Hi All: I'm processing GCxGC data obtained from a Q Exactive GC instrument and the MS binning options does not seem to be working. The accurate masses are displayed only with one decimal (e.g., 121.3). I have tried the 'Uniform Bin' with many bin sizes and the spectrum exhibited in the 'Spectrum' wi...

LRI

Dear all: My group is performing qualitative analysis and we needed the information listed below during the automated library search of the blob table: 1. similarity match; 2. experimental LRI; 3. LRI retrieved from the library search. In GC Image R.2.2, we have solved items 1 and 2 by customising t...
