# Read a file with data
# Gratiot<-read.delim("http://max2.ese.u-psud.fr/epc/conservation/BI/Complete.txt", , header=FALSE)

# Generate a formatted list nammed data_Gratiot

# Generate initial points for the optimisation

# Run the optimisation

data(result_Gratiot)
# Plot the phenology and get some stats
