Python-machine learning auto data

Python, pandas and numpy installation
solves the problem

C:\> setx PATH "%PATH%;C:\<path\to\python\folder>\Scripts"

C:\> pip install pandas


I wasted time to find out the correct url link:

BLAST-Basic Local Alignment Search Tool

Standalone BLAST on Linux machine:

BLAST detects regions of local similarities between sequences.

• How to Create your own database and search for the desired sequence?

1. First way is wget on command line;

which is $   wget ftp://ftp.ncbi.nih.gov/blast/db/FASTA/nr.gz

      $ wget -c ftp://ftp.ncbi.nih.gov/blast/db/FASTA/nr.gz 

-c means to continue

1. NCBI ftp website 

notes on Drummond et al "Why highly expressed proteins evolve slowly" paper

Some stuff:

30 years ago, Zuckerkandl proposed that a protein’s sequence will evolve at a rate primarily determined by the proportion of its sites involved in specific functions (or ‘‘functional density’’).

However, those effects in functional density and measurements of residues in protein functions remained unclear.

Nice article.

SQL

Adapted from codecademy.com SQL course:

• JOIN will combine rows from different tables if the join condition is true.
• LEFT JOIN will return every row in the left table, and if the join condition is not met, NULL values are used to fill in the columns from the right table.
• Primary key is a column that serves a unique identifier for the rows in the table.
• Foreign key is a column that contains the primary key to another table.
• CROSS JOIN lets us combine all rows of one table with all rows of another table.
• UNION stacks one dataset on top of another.
• WITH allows us to define one or more temporary tables that can be used in the final query.
