Cannot analyze MD simulation using GROMACS - error 127

Hi,

I tried to analyse my recently performed a MD simulation using GROMACS following a tutorial (Running molecular dynamics simulations using GROMACS ).
Parameters of the MD simulation were slightly modified to have shorter simulation (because my protein is around 350 residues).

I then tried to analyse the results following Bio3D tutorial (Analysis of molecular dynamics simulations).

Everything seemed to work fine exept when I tried to analyse the results. In fact lauchning RMSD Analysis using Bio3D resulted in " /corral4/main/jobs/046/826/46826281/tool_script.sh: line 9: Rscript: not found " alias " Fatal error: Exit code 127 ()"

Do you have an idea why?

Thank you so much,

Martin
