Hi Uday,
Thanks for your response.
I'm working with patient IDs and controls. I would like to to rename all the patient IDs as "sample" but keep the control IDs as they are. I have one column that contains the actual IDs (this is the column in which I would like to change some of the cells - the ones corresponding to patient ID), and another column that differentiates the patient IDs and controls. Under this column, there is either "sample", "positive control" or "negative control" in each cell. The cells with the "sample" option correspond to patient sample ID in the other column. So, I simply selected all the "sample" cells in one column and move to the other column to get all the patient IDs selected. Now I need to rename them.
I hope this is a bit clearer .
Thanks for the support.
