Hello everyone,
I am a pharmacist, studying my Master’s Degree in Medical Biotechnology. I am focused on bioinformatics.
Currently i am working on a project regarding the peptides used in cosmetic preparations and their properties. For this example, i was studying a peptide “Matrixyl” solution and it’s breaking point in thermal stress, and for preparing the simulation i have used the peptide example.
I am sharing with you my data.matrixyl (because of the length kindly access to from my git repo) and the in.peptide file*. I know they are a mass, i just want it to be compiled and get some results (couple of frames for a gif would be perfect).
Also simulation stuck like this:
