Hi Alex,

First, you need to setup a development environment. Follow the "Hot to start 
MZmine 2 development" tutorial: 
https://docs.google.com/document/pub?id=1P2Jy3IROmBT2dIggy9u5IK0rCFpT2HHOk1l_XTIrnps
Then you can try to make a copy of an existing module, and start changing the 
functionality of your copy.

It will certainly help to read some basic tutorial about Java. There are plenty 
on the Internet. As for R, you do not need to learn it. Most of MZmine is 
implemented in pure Java.

Best regards,

Tomas

Dear Tomas:

I don't have any experience of using Java language although I always would like 
to learn...just too busy (or lazy...).

Where would you recommend to start for a layman? Just follow Development page 
on the MZMine website? Do I need to read some basic material about Java? or how 
about R language? I want to try it by myself first...but as you said I do need 
your guide and help.

Many thanks in advance.

Alex

Subject: Re: [Mzmine-devel] Chloride and Bromide isotopic peaks

Hi Alex,

I agree that such function is relatively simple and it would be useful to have 
it in MZmine. However, currently I don't have the resources to work on new 
MZmine functions. If you like to develop it yourselves, or hire someone to do 
it, I can provide assistance.

Best regards,

Tomas

Dear Tomas:

My name is Alex and we have been using MZMine since 2.0. It is a very useful 
program to handle LC-MS data for metabolomics plus it is free of charge! Thanks 
for developing such a good software for us.

Now we have a request for MZMine to group/identify all related chloride and 
bromide isotopic peaks. I think it should not be difficult to conduct and the 
algorithm requires three conditions:

1, they should have very close retention times (within 0.1min).
2, the interval of m/z between is 1.997 for chloride and 1.998 for bromide.
3, the ratio of peak area/height determined by the number of chlorine/bromine, 
e.g. if there are 1 chlorines in the molecule the ratio of peak area/height 
should be about 3:1, if 1 bromine it's 1:1, if 2 chlorine it's 9:6:1, if 2 
bromine it's 1:2:1 and so on.

It is very useful to find/identify the compounds with chlorines or/and bromines 
in their molecules. This function can be added into the identification section 
or isotopes section.

What do you think? Please let me know if you need more information or 
explanation.

Many thanks

Alex
