metaXCMS / 0 values for first imported tsv file
I have problem with reading (?) tsv files by metaXCMS package in R. Here is the situation:
The pairwise comparison in xcms results with 5 tsv files. Then tsv files, let’s call them : 1.tsv; 2.tsv; 3.tsv; 4.tsv and 5.tsv are imported to metaXCMS. After choosing control and applying filters common features are found. Venn Diagram shows numbers in all circles but first one (in this case 1.tsv). Exported all features table shows values in all rows and columns except the columns from file 1 (numbers are replaced with NA). When the order of imported files is changed, let’s say: 2,3,4,5,1 then situation as describe above occurs, however, now the zero values/NA are put in place of file 2 and for file 1 (which was imported as last one) appropriated values are shown. I use 32 bit 2.15.1 R version and 0.1.19 metaXCMS version.
I would greatly appreciate comments and suggestions on this issue,
Best,
Monika
