Hi,
I'm Satoshi Tanaka, one of Mass++ developer.
The file format to import into peak matrix is
CSV (Comma Separated Values) or tab separated values
file.
You can export such a file on Excel. (*.csv or *.txt)
The first column is RT and the second column is m/z.
If [Read Charge] in the Import Peak Positions dialog is checked,
the third column is charge.
If you use tab separated values file (*.txt),
you should set "Tab [ ]" as a [Separator],
otherwise you should set "Comma [ , ]" as a [Separator].
In addition you can add additional information.
Appended Column 0 - Appended Column 7 means
addition columns.
Appended Column 0 is third (if not reading charge) or fourth (if reading charge)
column in the text file
Appended Column 1 is fourth (if not reading charge) or fifth (if reading charge)
column...
The attached file is example.
In this case, charge is not described so [Read Charge] in the Import Peak Positions
dialog should be unchecked.
If you want to p-value into the peak matrix, input column name in the Appended Column 0 and
set DataType "Real Number".
If you want to Group into the peak matrix, input column name in the Appended Column 1 and
set DataType "Text".
regards,
