When applying a template to a blob table, the reference MS filed in Blob Properties/Analysis is filled automatically. What does the reference MS refer to?

Reference MS is added when adding a blob to template. It is the spectrum of the blob, either peak (apex) or blob(integrated) MS, which depends on the following setting:
Configure > Settings > Library Search > Type of Spectrum

Thanks.
So is this reference MS of the template somehow matched to blobs when clicking "match template"? If so, how is this done - is there some type of similarity score calculated? Is is possible to manually compare the spectrum of the template to the blob spectrum?

You need to set
Qualifier CLIC to use Reference MS, for example,
You can let the program generate it automatically whenever adding a blob to template by Configure > Settings > Template > Auto CLIC > check
Create Qualifier CLIC.... You can find more details
here.
There is no visual comparison between Reference and Blob spectra. But you can compute the match factors between them after applying template by setting
Analysis CLIC to
, then add
aCLIC Result column to Blob Table.
