     **What it does**
 
-    This tool performs a projective transformation of the input (moving) points (with/without labels).
+    This tool performs a projective transformation of regions of interest (ROIs) defined by pixel (point) coordinates with/without labels.
+
+    About the format of point coordinates (and labels) in the input TSV table: 
+    1st column: x-coordinate; 
+    2nd column: y-coordinate; 
+    (optional) more column(s): point label(s) (numerical or categorical).
+    The top row of the table will be regarded as column headers.
