Beginner Problem - Data Conversion from .D to .mzXML

[Rob]

This is a very basic question, but I can't seem to figure out my
problem. I just downloaded TPP, and I am trying to convert my .D files
from an Agilent MS to .mzXML.

I open TPP and go to Analysis Pipeline. In "1. Input File Format' I
select "Agilent .d Directories." I then click on "Add Files" in "2.
Specify Directory(ies) to convert to mzXML."

I have added my .D files to "c: / Inetpub / wwwroot / ISB / data /"
and they are present when I click on "Add Files," but their size is 0
k and they do not convert. I transferred the .D files from to my
laptop which is where I downloaded TPP.

Any suggestions on how to get my .D to .mzXML?

Hi Rob,

You can get the standalone "Trapper" converter programmed by Natalie
Tasman here:
http://sourceforge.net/projects/sashimi/files/trapper%20%28MassHunter%20converter%29/

It's a MSDOS command line program. You should run the following
command:

"C:\Program Files\trapper\trapper.exe" -v -c --mzXML your_file.d
your_file.mzXML

Note: -v is to visualize the progress, -c is to centroid the data (you
can use -p to export mzXML profile data) and --mzXML is the output
format.

Hope that helps,
Let us know if that works for you now.

Best,

Ludovic

Hi Rob,

When I tried to use -p to convert profile data, I got following error:

ERROR at .\MHDACWrapper.cpp, 178:
HR = -2146233067
Error getting chromatogram
unable to open C:\users\y811s\desktop\MEF2.d with MassHunter interface

However,-c worked pretty well.

Do you know how to solve this problem?
