Introduction:

This tool takes a peak table file and a samples-to-group design file as inputs and outputs the averaged intensity of every compound in every group.

Input files:

1. Peak table file in Tab-delimited txt format, with the first column as the compound identifier and the others as samples.

For example:

AlignID	STDmix_GC_01	STDmix_GC_02	STDmix_GC_03
1	1486892478	561322777	3448620272
Nitrogen dioxide	5492977592	684434115	3265669981
Ethanol, 2-fluoro-	2265686433	4182838129	4365291513
3-Pentanone, 2,2,4,4-tetramethyl-	13390154	12612932	21155307
Hydrazine	14588107	8510918	7224351

2. Sample-to-group design file, Tab-delimited text file with two columns, "sample " and "group ".

For example:

STDmix_GC_01	Group1
STDmix_GC_02	Group1
STDmix_GC_03	Group2

Output files:

'group_aver_pkTable.txt', average intensity results in each group.

For example:

AlignID	Group1	Group2
1	1024107628	3448620272
Nitrogen dioxide	3088705854	3265669981
Ethanol, 2-fluoro-	3224262281	4365291513
3-Pentanone, 2,2,4,4-tetramethyl-	13001543	21155307
Hydrazine	11549512.5	7224351
