Hi Kumarswamy, You could go about looking for microRNAs within lncRNAs by identifying tracks that contain the RNAs and then using the Table Browser to intersect them.
To find relevant tracks, use the "track search" button (just beneath the main graphic in the Genome Browser), or browse the tracks in the "Genes and Gene Prediction Tracks" section. (There is a track called "sno/miRNA" and another called "lincRNAs...," but there may be others.) If you have not used the Table Browser before, there is a good introduction to it here: http://www.openhelix.com/cgi/tutorialInfo.cgi?id=28 also see the user's guide: http://genome.ucsc.edu/goldenPath/help/hgTablesHelp.html I tried doing an intersection by selecting the "linkRNA Transcripts" track in the Table Browser and using the "intersection: create" button to create a base-pair-wise intersection with the sno/miRNA track. This found one region of intersection, at chr11:2,017,989-2,018,061 (using the GRCh37/hg19 assembly). I hope this helps you get started.
