Glioblastoma (GBM) is a WHO Grade IV tumor with poor visibility, a high risk of comorbidity, and exhibit limited treatment options. Resurfacing from second-rate glioma was originally classified as either mandatory or optional. Recent interest in personalized medicine has motivated research toward biomarker stratification-based individualized illnes...
Chapter
Secretory proteins play an important role in the tumor microenvironment and are widely distributed throughout tumor tissues. Tumor cells secrete a protein that mediates communication between tumor cells and stromal cells, thereby controlling tumor growth and affecting the success of cancer treatments in the clinic. The cancer secretome is produced...

Question
As I have to convert gromacs xtc into DCD formats for some analysis using Bio3D. Does anyone have the mdtools catdcd (https://www.ks.uiuc.edu/Development/MDTools/catdcd/)? Kindly please share with me through google drive or drop box?
Note: Any alternative solution for conversion of xtc into dcd ? That also will be fine.
I will be thankful to you.

While running the command getting following error given below: 
do_dssp -s md.tpr -f md.xtc
Fatal error:
Not enough memory. Failed to calloc -1082130432 elements of size 4 for grps[j].nm_ind
Question
NVT steps Command : gmx grompp -f NVT.mdp -c EM.gro -p topol.top -n index.ndx -o nvt.tpr
Error:
Fatal error:
[ file strong_posre_make_ligand.itp, line 5 ]:
Atom index (4579) in position_restraints out of bounds (1-43).
This probably means that you have inserted topology section "position_restraints"
in a part belonging to a different molecule than you intended to.
In that case move the "position_restraints" section to the right molecule.
For more information and tips for troubleshooting, please check the GROMACS
Please help me out for this issue. I will be thankful to you.
Question
Here is my problem:
(1) a peptide about 10 amino acids
(2) target protein (an enzyme with known PDB structure file, and known active sites)
(3) how to find the most reliable binding site and the complex structure? (also need result like free energy)
Thank you!!!
Question
Dear All,
In a peptide (from Histone 3 ), on the 9th/14th position of Lysine we have done acetylation. Now, I have to run a simulation but I don't have force field parameters for acetylated Lysine residue. So, I would like to request, if anyone have any idea please suggest or if someone has the parameters for acetylated Lysine residue please send me the file. Thanking you.
Question
