kandi X-RAY | chromVAR Summary

chromVAR is a R library typically used in Artificial Intelligence, Genomics applications. chromVAR has no bugs, it has no vulnerabilities and it has low support. However chromVAR has a Non-SPDX License. You can download it from GitHub.

chromVAR is an R package for the analysis of sparse chromatin accessibility data from single cell or bulk ATAC or DNAse-seq data. The package aims to identify motifs or other genomic annotations associated with variability in chromatin accessibility between individual cells or samples. For a more detail overview of the method, please see the publication (pdf, supplement). For a paper evaluating chromVAR and other methods as a method for enabling clustering of single cells, see the preprint from Huidong Chen et al. Using kmers + PCA appears to be the best variant of chromVAR for clustering, but newer methods such as SnapATAC outperform chromVAR for the clustering tasks evaluated in the paper. chromVAR may be complementary to some other methods, as a way of annotating TF motif usage in cells & clusters rather than cluster identification or embedding.

QUESTION

Is there a way to permute inside using to variables in bash?

Asked 2021-Dec-09 at 23:50

I'm using the software plink2 (https://www.cog-genomics.org/plink/2.0/) and I'm trying to iterate over 3 variables.

This software admits an input file with .ped extention file and an exclude file with .txt extention which contains a list of names to be excluded from the input file.

The idea is to iterate over the input files and then over exclude files to generate single outputfiles.

Input files: Highland.ped - Midland.ped - Lowland.ped
Exclude-map files: HighlandMidland.txt - HighlandLowland.txt - MidlandLowland.txt
Output files: HighlandMidland - HighlandLowland - MidlandHighland - MidlandLowland - LowlandHighland - LowlandMidland

how to stop letter repeating itself python

I am making a code which takes in jumble word and returns a unjumbled word , the data.json contains a list and here take a word one-by-one and check if it contains all the characters of the word and later checking if the length is same , but the problem is when i enter a word as helol then the l is checked twice and giving me some other outputs including the main one(hello). i know why does it happen but i cant get a fix to it

ANSWER

Answered 2021-Nov-25 at 18:33

As I understand it you are trying to identify all possible matches for the jumbled string in your list. You could sort the letters in the jumbled word and match the resulting list against sorted lists of the words in your data file.

ANSWER

Answered 2021-Oct-12 at 20:28

You can match your non-X containing FASTA entries with the regex >.+\n[^X]+\n. This checks for a substring starting with > having a first line of anything (the FASTA header), which is followed by characters not containing an X until you reach a line break.

QUESTION

Does Apache Spark 3 support GPU usage for Spark RDDs?

Asked 2021-Sep-23 at 05:53

I am currently trying to run genomic analyses pipelines using Hail(library for genomics analyses written in python and Scala). Recently, Apache Spark 3 was released and it supported GPU usage.

I tried spark-rapids library start an on-premise slurm cluster with gpu nodes. I was able to initialise the cluster. However, when I tried running hail tasks, the executors keep getting killed.

On querying in Hail forum, I got the response that

That’s a GPU code generator for Spark-SQL, and Hail doesn’t use any Spark-SQL interfaces, only the RDD interfaces.

So, does Spark3 not support GPU usage for RDD interfaces?

...

ANSWER

Answered 2021-Sep-23 at 05:53

As of now, spark-rapids doesn't support GPU usage for RDD interfaces.

Source: Link

Apache Spark 3.0+ lets users provide a plugin that can replace the backend for SQL and DataFrame operations. This requires no API changes from the user. The plugin will replace SQL operations it supports with GPU accelerated versions. If an operation is not supported it will fall back to using the Spark CPU version. Note that the plugin cannot accelerate operations that manipulate RDDs directly.

Here, an answer from spark-rapids team

Source: Link

We do not support running the RDD API on GPUs at this time. We only support the SQL/Dataframe API, and even then only a subset of the operators. This is because we are translating individual Catalyst operators into GPU enabled equivalent operators. I would love to be able to support the RDD API, but that would require us to be able to take arbitrary java, scala, and python code and run it on the GPU. We are investigating ways to try to accomplish some of this, but right now it is very difficult to do. That is especially true for libraries like Hail, which use python as an API, but the data analysis is done in C/C++.

Usage of compression IO functions in apache arrow

Asked 2021-Jun-02 at 18:58

I have been implementing a suite of RecordBatchReaders for a genomics toolset. The standard unit of work is a RecordBatch. I ended up implementing a lot of my own compression and IO tools instead of using the existing utilities in the arrow cpp platform because I was confused about them. Are there any clear examples of using the existing compression and file IO utilities to simply get a file stream that inflates standard zlib data? Also, an object diagram for the cpp platform would be helpful in ramping up.

Answered 2021-Jun-02 at 18:58

Here is an example program that inflates a compressed zlib file and reads it as CSV.

Install chromVAR

The recommended installation method for chromVAR is using BiocManager. You will first have to have installed the BiocManager package . A number of needed packages are installed in this process. One of the dependencies has a system requirement for the gsl library, so if this is not installed already it may need to be installed separately. Several people have reported issues with the GO.db package (a dependency of one of the dependencies) not being installed automatically -- if you see an error relating to that package, try installing it separately first (BiocManager::install("GO.db")). For Windows users, some have reported that the S4Vector dependency does not currently function on windows R 3.3.3, but that installation was successful on R 3.3.2. For Mac users, some have encountered installation difficulties relating to compiling the C++ code. If you encounter problems, please see the threads and advice in Issues 11 and 20.
