+==========================
+Model temporal trend
+==========================
+
+This tool is an implementation of the gls function from RegionalGAM package:  https://github.com/RetoSchmucki/regionalGAM/
+
+This function model temporal trend with a simple linear regression.
+
+|
+
+**Outputs**
+
+The tool returns the linear regression model in an Rdata file.
+
+It also returns a summary of this model in txt format.
