29 Summary:
|
|
|
30 - The field `mz_tab_info` was added in new table smol_xcms_set.
|
|
|
31
|
|
|
32 smol_xcms_set table added
|
|
|
33 -----
|
|
|
34 This table contains a subset of the original ms file.
|
|
|
35
|
|
|
36 mz_tab_info field added to smol_xcms_set
|
|
|
37 -----
|
|
|
38 This field contains five subfields:
|
|
|
39 - sampclass ;
|
|
|
40 - sampnames ;
|
|
|
41 - rtmed ;
|
|
|
42 - mzmed ;
|
|
|
43 - smallmolecule_abundance_assay .
|
|
|
44
|
|
|
45 These fields were added after users asked to export data from XSeeker
|
|
|
46 in mzTab files.
|
|
|
47 XCMS has some functions to extract sampclass, sampnames, rtmed, mzmed
|
|
|
48 and smallmolecule_abundance_assay from xcms set. Then, they are used
|
|
|
49 in the mz tab creation process, but we didn't want to keep the whole
|
|
|
50 xcmsset object. So we used the original code from XCMS and modified it
|
|
|
51 a little bit, justifying the extraction of these new fields.
