Dear mzwiff users
I was trying to convert ABI4000 *.wiff format file to mzXML using
standalone mzwiff (v. 4.3.1).
Strangely, it works for some files, but not for others.
For the exactly same file, it gives working and not-working mzXML
output files in different computers.
The problem I found so far is that the not-working mzXML file has the
following:
In just a few scans out of thousands, some scan has "AAAAAAAAAAA" in
the <peaks></peaks> block
as shown below (right above the </scan> tag below)
<scan num="2857"
msLevel="1"
peaksCount="0"
polarity="+"
scanType="Q1 Scan"
retentionTime="PT1728.74S"
lowMz="0"
highMz="0"
basePeakMz="0"
basePeakIntensity="0"
totIonCurrent="0" >
<peaks precision="32"
byteOrder="network"
contentType="m/z-int"
compressionType="none"
compressedLen="0" >AAAAAAAAAAA=</peaks>
</scan>
In addition, most of the parameters are set to "0" (peaksCount, lowMz,
etc)
Does anyone know how to fix this problem?
Thanks.
