RNA file A must be in the format of fasta. It's important to note that the name of RNA fasta file must end with ‘A’, such as ‘sampleRNAfileA.fasta’. RNA fasta file A could be downloaded and the fasta file format could be checked.

RNA file B must be in the format of fasta. It's important to note that the name of RNA fasta file must end with ‘B’, such as ‘sampleRNAfileB.fasta’. RNA fasta file B could be downloaded and the fasta file format could be checked.

For the RNA-RNA interacting file, it must be csv format and its name can only be ‘RNA-RNA-Interacting.csv’. In the RNA-RNA interacting file, the sequence ID of RNA files A and B are required in the first and second columns, while the third column is the label which the column name can’t be changed. The RNA-RNA interacting file could be downloaded.
