How to execute Unix/shell commands in PHP?
Besides, Python & Perl, PHP is another language mostly used in bioinformatics programming. In this article, we provide a simple command to execute shell commands in a PHP script.
shell_exec()
It runs command via shell and returns the output as a string.
syntax: $output = shell_exec($command);
If you are using variables inside your command, you need to use escapeshellarg().
syntax: $output = shell_exec($command);
Let’s assume, if you are running the blastp command on a query file with a variable filename, then it could be run like this:
$output = shell_exec("blastp -query ".escapeshellarg($filename.'.fasta')." -db /path/to/db -out output.txt");

vs_analysis_compound.py: Python script to search for binding affinities based on compound names.
Previously, we have provided the vs_analysis.py script to analyze virtual screening (VS) results obtained from Autodock Vina. In this article, we have provided another script to search for binding affinity associated with a compound. (more…)
In this article, we provide a simple Python script to download files from an FTP server using Python. (more…)
VMD allows converting PDB to PSF format but sometimes it gives multiple errors. Therefore, in this article, we are going to convert PDB into PSF format using a different method. (more…)
