BRAIN DAMAGING HABITS

BRAIN DAMAGING HABITS

1. No Breakfast
People who do not take breakfast are going to have a lower blood sugar level.
This leads to an insufficient supply of nutrients to the brain causing brain degeneration.

2. Overeating
It causes hardening of the brain arteries, leading to a decrease in mental power.

3. Smoking
It causes multiple brain shrinkage and may lead to Alzheimer disease.

4. High Sugar consumption
Too much sugar will interrupt the absorption of proteins and nutrients causing malnutrition and may interfere with brain development.

5. Air Pollution
The brain is the largest oxygen consumer in our body. Inhaling polluted air decreases the supply of oxygen to the brain, bringing about a decrease in brain efficiency.

6. Sleep Deprivation
Sleep allows our brain to rest. Long term deprivation from sleep will accelerate the death of brain cells.

7. Head covered while sleeping
Sleeping with the head covered increases the concentration of carbon dioxide and decrease concentration of oxygen that may lead to brain damaging effects.

8. Working your brain during illness
Working hard or studying with sickness may lead to a decrease in effectiveness of the brain as well as damage the brain.

9. Lacking in stimulating thoughts
Thinking is the best way to train our brain, lacking in brain stimulation thoughts may cause brain shrinkage.

10. Talking Rarely
Intellectual conversations will promote the efficiency of the brain.

How to keep chain ID / IDs in GROMACS?

In GROMACS , while converting pdb file (monomer or multimer) into .gro file, it do not preserve the chain ID information. Due to the lack of chain ID information, pdb file retrieved from .gro file at any stage of the simulation has missing chain IDs and pdb file can not be visualized properly in PYMOL / RASMOL . There are two ways to convert .gro file into .pdb Lets say your protein name is xyz.pdb 1] gmx editconf -f xyz.gro -o xyz.pdb 2] gmx trjconv -f xyz.gro -o xyz.pdb -s xyz.tpr Only ' trjconv ' will retrieve the chain ID information for all the chains. and not ' editconf '. If you have monomer protein and wish to assign any chain ID then following command will be of your interest: gmx editconf -f xyz.gro -o xyz.pdb -label [ chain-ID ]

GNUPLOT: How to draw trend line?

How to draw trend line in the GNUPLOT? If you like to plot graphs in gnuplot and dont know how to plot trendline then here you are. Follow the steps mentioned below... 1. You should have a files with X and Y values 2. Open GNUPLOT (Operating system dosen't change anything here. It works on all systems) 3. Type the command in the gnuplot terminal Lets say I have a file for eg. '1.txt' p '1.txt' u 1:2 w d title '', '1.txt' u 1:2 smooth acsplines title '1.txt' OR p '1.txt' u 1:2 w d title '', '1.txt' u 1:2 smooth bezier title '1.txt' It will plot as below...

Python : Turtle tree

Turtle module can be used to draw some very nice patterns in Python. Following are some examples with code. ==================== import turtle import random t = turtle.Turtle( shape = "circle" ) t.lt( 90 ) lv = 14 l = 120 s = 30 t.color( 'indigo' ) t.width(lv) t.penup() t.bk(l) t.pendown() t.fd(l) def draw_tree ( l , level ): width = t.width() # save the current pen width t.width(width * 3.0 / 4.0 ) # narrow the pen width l = 3.0 / 4.0 * l #t.color(R,G,B) #provide the RGB numbers t.color(random.random(), random.random(), random.random()) t.lt(s) t.fd(l) if level < lv: draw_tree(l, level + 1 ) t.color(random.random(), random.random(), random.random()) t.bk(l) t.rt( 2 * s) t.fd(l) if level < lv: draw_tree(l, level + 1 ) t.color(random.random(), random.random(), random.random()) t.bk(l) t.lt(s) t.width(width) # restore the previous pen width t.speed( "fastest" ) draw_tree(l, 5 ) turtle.done() ===========

MD convert (xtc to dcd)

CATDCD program can be used to convert one file format to another file format. For example: How to convert trajectory output of GROMACS .xtc format into NAMD .dcd format ==== /path/to/catdcd -o /path/to/save/file/abc.dcd -xtc /input/path/to/save/file/abc.xtc ==== How to install CATDCD? Follow the link- https://www.ks.uiuc.edu/Development/MDTools/catdcd/ Download the catdcd-X.Xx.tar.gz Extract all files from the tar. Locate the catdcd file. It should be in directory : catdcd-4.0b/LINUXAMD64/bin/catdcd4.0/ Source the catdcd in your bashrc: export PATH="/path/to/catdcd/directory/:$PATH"
