Hello,
I have heard a lot about MZmine and find it very interesting. However I
got stock with a few problems and I hope you will be able to help me
solve them.
My first problem is that I have problems allocating enough memory to
MZmine. I can force MZmine to allocate 1 GB but (as in the attached .bat
file), but if I try to allocate more I get the following error:
And if I try to run the original script (where half the memory should be
allocated to MZmine) I get this result:
Do you have any idea on how I can get more memory allocated? 1 GB is not
enough for my dataset and I get memory problems when I run the
chromatogram builder.
My second problem is that MZmine have problems communicating with R when
I try to do baseline correction.
The output you request in your manual from the command prompt are:
.libPaths()
   [1] "C:/Users/Lea/Documents/R/win-library/3.1"
   [2] "C:/Programmer/R/R-3.1.2/library"
When I try to run the packageDescriptions I get an error: " Could not
find function "packageDescription" " - So I probably have a problem with
my R installation, but I do not know how to fix this. I you could give
me a hint I would very much appreciate it :-)
Some system information:
MZmine: is the newest version just downloaded a week ago.
R (64 bit):
version: 3.1.2
Location on computer: C:\Programmer\R\R-3.1.2
rJava location: C:\Users\Lea\Documents\R\win-library\3.1\rJava\jri\x64
My computer:
64-bit processor, 32 GB RAM, Windows 8.
Kind regards
