Normalization to ISTD should deselect samples that do not contain ISTD

Dear all,

my questions might be annoying to the expert users but I still have a longer wish list for MS-DIAL  :D

These days I have realized that MS-DIAL does not remove samples from the statistics that lack the normalization STD. In my case I analyzed some solvent blanks which I treated as additional blanks (beside my process blanks). When I normalize to my internal STD almost all peaks are normalized, except for these blanks. This is a plausible behaviour but a further analysis of these (non-normalized) samples should be avoided, right?

What if MS-Dial deselects all samples that haven't been normalized properly for the further analysis?

Just an idea,

Stefan

Simply, please exclude your blank samples from
"Option" -> "File property setting".
Then, you can do further analysis without the samples, and you will be able to see the basic statistics like bar/box charts without those as well in MS-DIAL.
Thanks,
