I am using PyMol with PyTMs plugin to visualize possible phosphorylation sites on a protein. I am wondering how I can use the program to calculate and show an optimized protein structure to avoid steric clashes.
Not sure about pymol, but you can use available energy minimization servers such as Chiron (https://dokhlab.med.psu.edu/chiron/login.php)
I used I-TASSER to predict the 3D structure of my protein of interest and PyMOL with APBS plugin to add a surface showing the electrostatic potential. Then, with PyTMs plugin, I added three...

I have one lane and samples from two experiments (RNA and ChIP). Is there an option to sequence them together? I am afraid that RNA samples will "eat" all the reads. Thank you for any suggestion!
