WAP for reading a sequence file from D: drive, convert it into a FASTA format and save in a diff file at C: drive with name protein.fasta

Here is a Python script that reads a sequence file from D: drive, converts it into a FASTA format and saves it in a different file at C: drive with the name protein.fasta.

from Bio import SeqIO

# Step 1: Read the sequence file from D: drive
sequence_file = "D:/sequence.txt"
sequences = SeqIO.parse(sequence_file, "fasta")

# Step 2: Convert it into a FASTA format
fasta_sequences = [sequence.format("fasta") for sequence in sequences]

# Step 3: Save in a different file at C: drive with name protein.fasta
output_file = "C:/protein.fasta"
with open(output_file, "w") as output_handle:
    SeqIO.write(fasta_sequences, output_handle, "fasta")

Please replace "sequence.txt" with your actual sequence file name. This script uses Biopython, a set of freely available tools for biological computation. If you haven't installed it yet, you can do so by running pip install biopython in your command line.

This script assumes that the input file is already in FASTA format. If it's not, you'll need to adjust the parsing and conversion steps accordingly.
