miRBench datasets

Changelog

PhyloP and PhastCons conservation scores for the target gene sequence have been added to the test/train/leftout datasets as two additional columns - 'gene_phyloP' and' gene_phastCons'. 

Both of new columns contain list of conservation scores rounded to 3 decimal places, one score for each nucelotide in the gene sequence.

PhyloP and PhastCons scores were obtained from:

• https://hgdownload.cse.ucsc.edu/goldenPath/hg38/phyloP100way/hg38.phyloP100way.bw
• https://hgdownload.cse.ucsc.edu/goldenpath/hg38/phastCons100way/hg38.phastCons100way.bw

Dataset Summary

The following listed datasets were recreated via a series of post-processing pipelines (available here) to eliminate a bias between the positive and negative classes (miRNA family imbalance) discovered in previous versions of the datasets. All have a 1:1 positive to negative class ratio. 

• AGO2_eCLIP_Manakov2022_leftout.tsv.gz
• AGO2_eCLIP_Manakov2022_test.tsv.gz
• AGO2_eCLIP_Manakov2022_train.tsv.gz
• AGO2_eCLIP_Klimentova2022_test.tsv.gz
• AGO2_CLASH_Hejret2023_test.tsv.gz
• AGO2_CLASH_Hejret2023_train.tsv.gz

The following listed dataset is the concatenated HybriDetector output of all the selected samples from the available Manakov sample files. It therefore contains only a raw version of the positive class of the Manakov dataset. It is the input to the series of post-process pipelines for the Manakov dataset.

The other inputs to the post-process pipelines for the Hejret and Klimentova datasets are found at the following links. 

• Hejret dataset
• Klimentova dataset

The structure of each dataset is consistent, with the following column order:

1. gene: A string of length 50 indicating the binding site sequence in the 5’ to 3’ direction.
2. noncodingRNA: A string of variable length (16–28) indicating the mature miRNA sequence in the 5’ to 3’ direction.
3. noncodingRNA_name: A string indicating the name of the miRNA.
4. noncodingRNA_fam: A string indicating the name of the miRNA family the miRNA belongs to.
5. feature: A string indicating the feature annotation on the genome where the binding site occurs.
6. label: A boolean value indicating whether the example belongs to the positive or negative class.
7. chr: A string indicating the chromosome number on the genome where the binding site occurs.
8. start: An integer indicating the 1-based start position of the binding site on the genome.
9. end: An integer indicating the 1-based end position of the binding site on the genome.
10. strand: A string indicating whether the binding site occurs on the ’+’ or ’-’ strand on the genome.
11. gene_cluster_ID: An integer indicating the cluster ID of the binding site sequence used to generate the negative class.

Note that the binding sites reported in all datasets are consistent with GRCh38.
