Application Details

• Description: Local accelerated base calling for Nanopore data.
• Version: 4.2.2, 6.1.7 and 6.4.2
• Modules: guppy/cpu/4.2.2, guppy/cpu/6.1.7 and guppy/cpu/6.4.2
• Modules: guppy/gpu/4.2.2, guppy/gpu/6.1.7 and guppy/gpu/6.4.2
• Licence: Free, open-source

• Note: guppy version 3 is now removed from production.

Usage Examples

Using the GPU as an accelerator will make the analysis considerably faster (on large data sets). For small runs, the CPU version is recommended and probably faster by removing the GPU overhead.

Batch example

#!/bin/bash
#SBATCH -J guppy.job
#SBATCH --exclusive
#SBATCH -o gpu.%j.out
#SBATCH -e gpu.%j.err
#SBATCH -p gpu
#SBATCH --gres=gpu
#SBATCH --exclusive

module purge
module load cuda/10.1.168
module load guppy/gpu/6.4.2

guppy_basecaller --input_path /home/user/folderIN --save_path /home/user/folderOUT --flowcell FLO-MIN106 --kit SQK-RPB004 --min_qscore 7 --qscore_filtering -x cuda:0
