Re: Possible to extract hit mass spec from NIST to blob table?

No, hit spectra are not directly available. When viewing a blob spectrum, the software retrieves the hit spectra from NIST library on the fly. It could be done by a custom plugin , or searching NIST MS Search program again in your own program. Both are time-expensive operations. The plugin would be ...

Re: MSSTRING() and decimals

The software always imports centroid data if it is available. If centroid data is not available, the software will import nominal spectra of profile data. From the screenshots, there are centroid spectra. So, the only problem is MS Data Binning setting. By default, MSString() uses the Blob spectrum....

Re: MSSTRING() and decimals

Try the following expression MSSTRING@peak("mzDecimal=4") If m/z values have the correct decimal places, check if Configure > Settings > Multi-Channel > MS Data Binning settings are set to By Integer Intervals . If m/z values still only have one decimal ".0" , it is probably beca...

Re: Automatic/batch library search?

No, unfortunately mass calibration cannot be done in batch processing at this moment. You may look into your MS instrument software that might have some option to calibrate masses during acquisition.

Re: Automatic/batch library search?

Right now, the option is part of the Library Search Configuration. You will need to modify the configuration of the method. Configure > Settings > Search Library > check Perform library lookup after blob detection automatically https://www.gcimage.com/downloads/guide/LibSearchAfterDetectBlobSetting....

Re: Import of MSMS data in GC Image

Here is a quick check list: Does the program report any error when Import Image? Check here for a MassHunter-related problem. After Import, does the TIC look normal? In order to generate a 2D chromatogram image, raw data need to be uniformly sampled. But almost any MS/MS mode results in non-uniform ...

Re: Import of MSMS data in GC Image

Can you import the data and see a normal 2D TIC in GC Image?
