Import a batch of files
Hi, Is there a way to do multiple file importation (e.g. shimadzu .gqd files to .gci)? I noticed that when I save an XML script, it only records the parameters applied after opening the imported file like phase roll, baseline corr, etc. The app GUI during importation also has initial parameters like...

Re: Library search - NIST MS search
I am using the NIST 2020 version.
I think I just had some different configuration with the NIST MS Search program. When I set the GC image library search configuration to "interactive" and not "batch", hitlist result is consistent.
Thank you!

Library search - NIST MS search
Hello, I did a library search in GC image (default configuration). I have noticed that when I try to check on a single blob, view its spectrum and click on search with NIST MS search program from the MS spectrum window, the hit list result changes from the initial results. I have tried the "syn...

Re: Blob analysis - chemometrics
Thank you very much for your responses. I have a follow-up question (though this might be for another forum topic). I am exploring the m/z intensities (baseline corrected in default MS mode) for use in a prediction model. However, I noticed that some of m/z intensity values are in negative values. I...

Blob analysis - chemometrics
Dear All, In the current version of GC image, there is a possibility to analyze blobs through PCA. Are the raw data of the blobs based on m/z signal in the whole blob area or the peak area only? Is there a reference documentation on how GC image does the preprocessing and PCA on the raw data? Also, ...
