This is a advanced feature enabling users to profile expression of novel miRNA (maximum 5 sequences for which no pre-computed expression profile is available in latest release of PmiRExAt).The submitted new miRNAs sequences will be profiled (expression abundance ) against database of pre-formatted datasets of wheat(21),rice(53) and maize(43).List of all miRNA present in PmiRExAt database can be accessed on 'Related data' tab.

These custom search jobs are computationally very intensive. Normally it takes about ~90 minutes to profile miRNA abundance of 5 miRNA sequences in database of 2.4 billion+ small RNA sequence reads. Results of the submitted job will be emailed to you automatically by the web-server.
