Hi,

I am trying to use MZmine 2.10 (no modify; OS: windows XP) that was downloaded 
from the webset of MZmine 2 home page for my MS data processing.  These data 
(.wiff) were derived from ABI MS system using Precursor Ion Scan mode.  The 
original data (.wiff) were translated to the format of mzData file.  I use the 
mzData file for data processing in MZmine 2.10.  I had tried two modules:
1) Raw data methods > Mass detection (Mass detector: Centroid; MS level: 2; 
Mass list name: masses1) > Chromatogram builder (Mass list: masses1; Min time 
span (min): 0.1; Min height: 100; m/z tolerance: 0.2; Suffix: chromatograms)
2) Raw data methods > MS/MS peaklist builder (m/z window: 0.1; Time window: 
0.1; MS level: 2)
Both could not make the showing of peak list (as shown in attachment).  
However, the 2D and 3D chromatograms can be displayed.  Differently, another MS 
data that was acquired by Q1 Full Scan mode could be processed using the module 
as below:
Raw data methods > Mass detection (Mass detector: Centroid; MS level: 1; Mass 
list name: masses2) > Chromatogram builder (Mass list: masses2; Min time span 
(min): 0.1; Min height: 100; m/z tolerance: 0.2; Suffix: chromatograms)

Why it couldn't be operated for data file derived from Precursor Ion Scan mode. 
 If anybody can please make me the points in the problem I met?  Thank you for 
your time!

Have a nice day

Tang, Chuan-Ho
