31
+
32
+ bpRNA-1m is a database of single molecule secondary structures annotated using bpRNA.
33
+
34
+ ## Disclaimer
35
+
36
+ This is an UNOFFICIAL release of the [bpRNA-1m](https://bprna.cgrb.oregonstate.edu/index.html) by Center for Quantitative Life Sciences of the Oregon State University.
37
+
38
+ **The team releasing bpRNA did not write this dataset card for this dataset so this dataset card has been written by the MultiMolecule team.**

52
+
53
+ ## Column Description
54
+
55
+ The converted dataset consists of the following columns, each providing specific information about the RNA secondary structures, consistent with the bpRNA standard:
56
+
57
+ - **id**:
58
+ A unique identifier for each RNA entry. This ID is derived from the original `.sta` file name and serves as a reference to the specific RNA structure within the dataset.
59
+
60
+ - **sequence**:
61
+ The nucleotide sequence of the RNA molecule, represented using the standard RNA bases:
62
+
63
+ - **A**: Adenine
64
+ - **C**: Cytosine
65
+ - **G**: Guanine
66
+ - **U**: Uracil
67
+
68
+ - **secondary_structure**:
69
+ The secondary structure of the RNA represented in dot-bracket notation, using up to three types of symbols to indicate base pairing and unpaired regions, as per bpRNA's standard:
70
+
71
+ - **Dots (`.`)**: Represent unpaired nucleotides.
72
+ - **Parentheses (`(` and `)`)**: Represent base pairs in standard stems (page 1).
73
+ - **Square Brackets (`[` and `]`)**: Represent base pairs in pseudoknots (page 2).
74
+ - **Curly Braces (`{` and `}`)**: Represent base pairs in additional pseudoknots (page 3).
75
+
76
+ - **structural_annotation**:
77
+ Structural annotations categorizing different regions of the RNA based on their roles within the secondary structure, consistent with bpRNA standards:
78
+
79
+ - **E**: **External Loop** – Regions that are unpaired and external to any loop or helix.
80
+ - **S**: **Stem** – Paired regions forming helical structures.
81
+ - **H**: **Hairpin Loop** – Unpaired regions at the end of a stem, forming a loop.
82
+ - **I**: **Internal Loop** – Unpaired regions between two stems.
83
+ - **M**: **Multi-loop** – Junctions where three or more stems converge.
84
+ - **B**: **Bulge** – Unpaired nucleotides on one side of a stem.
85
+ - **X**: **Ambiguous** or **Undetermined** – Regions where the structure is unknown or cannot be classified.
86
+ - **K**: **Pseudoknot** – Regions involved in pseudoknots, where base pairs cross each other.
87
+
88
+ - **functional_annotation**:
89
+ Functional annotations indicating specific functional elements or regions within the RNA sequence, as defined by bpRNA:
90
+ - **N**: **None** – No specific functional annotation is assigned.
91
+ - **K**: **Pseudoknot** – Marks nucleotides involved in pseudoknot structures, which can be functionally significant.
92
+
93
+ ## Variations
94
+
95
+ This dataset is available in two variants:
96
+
97
+ - [bpRNA-1m](https://huggingface.co/datasets/multimolecule/bprna): The main bpRNA-1m dataset.
98
+ - [bpRNA-1m(90)](https://huggingface.co/datasets/multimolecule/bprna-90): bpRNA_1m(90) is a subset of bpRNA_1m containing RNAs with less than 90% sequence similarity.
