Hello! I am working in Mass Profiler Professional software (MPP), can someone explain to me what are the attributes that can be added to the samples, please?

Hello
i use masshunter profiler .
This software is primarily designed to compare untargeted analysis , when there is no target compound
such as environmental samples ( soil and water samples) , or metabolism samples.
software can also identify the unknowns and compare them
it's very good choice for researchers and universities , it's not designed for QC work
for example this for a comparison of two samples , profiler identified the peaks and compared them
Profiler detects every possible compound according to algorithm called Q score
so Q score means probability of spectrum to be a compound , less Q score means the spectrum may be a noice
you can se you Q score criteria , also your abundance criteria
this is the first thing .
then in the table he will group the compounds according to Rt , area , and Q score , so you can compare the 2 groups
if compound is detected in on group but not in the other you will find one result for it only while the other sample results will be empty and log A1/A2 is high ( 16 which is very high ) like in the lower picture
but notice that most of them are usually noice so you need to neglect them or to increase your abundance and Q score criteria
...
after grouping you can mark some of them and compare them graphically
also you can identify the compound using Nist library if it is GC MS or other useful library if you are using LC QTOF
I think we are not talking about the same thing. These are the attributes I am refering to, it accept files type .txt, .csv and .tsv.
LOL , it is not found in my version that why i didn't understand you
i am using masshunter profiler 10
sorry
