If you have several files and samples with many study variables to set (sample type, quantification channel, study factors), you can set values for study variables for multiple samples at once. You can use either the cursor or the keyboard to set these values on the Samples page.
You can also use multicell editing on the Samples page to enter factor values for several samples. You can use the filter option on the Samples page to filter on any term, and then perform the change on the filtered list.
Procedure
- Select the Samples tab.
- Select the gray arrow next to the first sample on the Samples page to expand the information about the sample.
- Set the value for the factor for each sample in each raw data file by doing one of the following:
- Select the dropdown in the factor column and then select the value from the list.
- Enter the first letter of the study factor in the cell and it will auto-populate.
- The following figure shows the Samples page of a study, where the factor being defined (the E coli (ng) factor) is shown in the far-right column of the table.
- The following figure shows the Samples page of a study with all of the factors that you set. It displays the same sample information as the Input files page.
