Specifically the sample names, but also data file names if possible.
You can change sample names in the injection list and reprocess data. I don't know if there is a way to change data file name - i suspect not.
You are correct. The sample name can be edited in the Injection List and the updated name will be saved in the results the next time the result set is reprocessed. The data file name cannot be changed after Acquisition, and the fields in this column will be grayed out in the injection list to reflect this.
