Step1: Please install the following
MAFFT 7.471 (install MAFFT: https://mafft.cbrc.jp/alignment/software/source.html)
Step2: Clone FPredX by
git clone https://github.com/johnnytam100/FPredX.git
Step3: Install required packages
pip install --no-cache-dir -r requirements.txt
Done!
Simply
cd ./FPredX
cp (path to your fluorescent proteins fasta) ./
python FPredX_predict.py -m /usr/local/bin/mafft -p example.fasta
(1) Insertions that cannot fit into the aligned FP sequences of the original FPredX dataset were removed to maintain the total number of features.
Higher the number of insertions removed, lower the prediction accuracy.
Check if any insertions were removed from the above log records of MAFFT OR confirm with the multiple aligned fasta file FPredX_mafft_predict.fasta generated during prediction.
(2) If position-residue pairs from the sequences submitted for prediction were not present in the aligned FP sequences of the original FPredX dataset, all zeros were assigned to the positions for prediction.
Higher the number of position-residue pairs reported, lower the prediction accuracy.
Check for locations of the position-residue pairs from the multiple aligned fasta file FPredX_mafft_predict.fasta generated during prediction.
