Source files

3-state, 8-state secondary structure and disorder prediction based on SeqVec

Create a new conda environment with all dependencies installed

kipoi env create SeqVec/structure
source activate kipoi-SeqVec__structure

Install model dependencies into current environment

kipoi env install SeqVec/structure

Test the model

kipoi test SeqVec/structure --source=kipoi

Make a prediction

kipoi get-example SeqVec/structure -o example
kipoi predict SeqVec/structure \
  --dataloader_args='{"fasta_file": "example/fasta_file"}' \
  -o '/tmp/SeqVec|structure.example_pred.tsv'
# check the results
head '/tmp/SeqVec|structure.example_pred.tsv'

Get the model

import kipoi
model = kipoi.get_model('SeqVec/structure')

Make a prediction for example files

pred = model.pipeline.predict_example()

Use dataloader and model separately

# Download example dataloader kwargs
dl_kwargs = model.default_dataloader.download_example('example')
# Get the dataloader and instantiate it
dl = model.default_dataloader(**dl_kwargs)
# get a batch iterator
it = dl.batch_iter(batch_size=4)
# predict for a batch
batch = next(it)
model.predict_on_batch(batch['inputs'])

Make predictions for custom files directly

pred = model.pipeline.predict(dl_kwargs, batch_size=4)

Get the model

library(reticulate)
kipoi <- import('kipoi')
model <- kipoi$get_model('SeqVec/structure')

Make a prediction for example files

predictions <- model$pipeline$predict_example()

Use dataloader and model separately

# Download example dataloader kwargs
dl_kwargs <- model$default_dataloader$download_example('example')
# Get the dataloader
dl <- model$default_dataloader(dl_kwargs)
# get a batch iterator
it <- dl$batch_iter(batch_size=4)
# predict for a batch
batch <- iter_next(it)
model$predict_on_batch(batch$inputs)

Make predictions for custom files directly

pred <- model$pipeline$predict(dl_kwargs, batch_size=4)

Get the docker image

docker pull haimasree/kipoi-docker:seqvec

Get the activated conda environment inside the container

docker run -it haimasree/kipoi-docker:seqvec

Test the model

docker run haimasree/kipoi-docker:seqvec kipoi test SeqVec/structure --source=kipoi

Make prediction for custom files directly

# Create an example directory containing the data
mkdir -p $PWD/kipoi-example 
# You can replace $PWD/kipoi-example with a different absolute path containing the data 
docker run -v $PWD/kipoi-example:/app/ haimasree/kipoi-docker:seqvec \
kipoi get-example SeqVec/structure -o /app/example 
docker run -v $PWD/kipoi-example:/app/ haimasree/kipoi-docker:seqvec \
kipoi predict SeqVec/structure \
--dataloader_args='{'fasta_file': '/app/example/fasta_file'}' \
-o '/app/SeqVec_structure.example_pred.tsv' 
# check the results
head $PWD/kipoi-example/SeqVec_structure.example_pred.tsv
