Does anybody know what is the difference between EI similarity score and Dot Product similarity score for GC-MS?
They both are in the Compoud Detail section or in the Compoud Serch Window. I know how the dot product works, but I don't understand how IE similarity differs from the dot product.
Does MS-DIAL handle batch alignment for GC-MS data?
I know you are asked to indicate the batch ID in the project settings, but I am not clear if that information are used for doing batch alignment during the process.
How should missing values have to be represented before using LOWESS/Spline normalization software? They should be represented with zeros "0", "NA", or only blank cells.
Or do you recommended firstly doing missing values imputation and then doing LOWESS/Spline normalization for batch/signal correction?
