Title: Retention Time in text files - Missing peak start and missing peak end
Post by: Tony on August 28, 2020, 04:32:53 AM
There is unfortunately no column in the export files from MSDIAL about the retention time (RT) from the peak begin and the peak end, just RT is given. Would it be possible to have that included?

Hi Tony,

the current version of MS-DIAL does not provide the edge RT for the alignment result.
You can check the peak left- and right retention times in each processed file by
export -> peak list export
function.
Sorry for your inconvenience.

Hiroshi

Hello Hiroshi,

i maybe wrong, but there is no peak left- and right retention times in each processed after the peak list export.
There is only retention time (RT averaged) for each peak and each sample given, but I cannot see any peak start/peak end.

kind regards
Tony

Hi Tony,

please do
1. Export -> Peak list result
2. Choose "txt" for export format
3. Choose "centroid" or "deconvoluted" for spectra type
4. Set your directory and files that you wanna export

Again, in the alignment result, MS-DIAL does not have the function to export the retention times of peak left- and right edges.
But you can check the edge's retention times for each peak of each file by the above way.
Thanks,

Hiroshi
