After the download is complete, uncompress the file "GPApred_standalone.tar.gz" by using the following command:
               a)  On Linux: tar -xvzf GPApred_standalone.tar.gz
               b) On Windows: To uncompress files with .tar.gz extension on Windows, follow the instructions on this page: https://www.winzip.com/en/learn/file-formats/tar-gz/
        Uncompressing the file will create a directory named GPApred_standalone
        Go to this directory and follow the instructions as follows:
###############################################################################################################
1. To run GPApred locally, the only requirement is to install R programming environment on your system.
   R is a free software environment for statistical computing and graphics and can be downloaded from this link (https://www.r-project.org/).
   R is easy to install and can be installed on UNIX/LINUX, Windows and MacOS systems. More information on installation can be found on this link (https://intro2r.com/install-r.html).

2. Once R is installed on your system, please install the package protr within the R environment:
        install.packages("protr")


3. Before running the script edit the name of input file on line No. 9;
 e.g. change data/input.fasta to your_input_file.fasta

OR

if you don't want to change the name of default input file name (input.fasta), remove the original input.fasta from the data directory and name your sequence file as input.fasta.

4. Make predictions by using the following command.

####### On linux terminal:
                Rscript server.R
OR

Within R environment
                source("server.R")

5. On the successful execution of the above command a comma separated file (csv) file should be generated in the "data" direcotry.
        For example: prediction_results.csv = Prediction results showing whether the given sequence is a GPA-anchor (P) or non-GPA anchor (X) domain containing protein.

The probability values are also provided in both the above mentioned files.
