Annotation of long non-coding RNAs

Question

[jain72744]

I have extracted multiple datasets from GEO database. However, I am unable to discern the appropriate IDs for the inputs. I have the sequences but on preforming nBLAST, I got multiple hits with 100% similarity. Kindly guide me for the same.

GPLs:   
GPL21827    Agilent-079487 Arraystar Human LncRNA microarray V4 (Probe Name version)
GPL20822    CapitalBio custom Human LncRNA array

I am not sure exactly what you are asking but the annotations for these GPL's is available as a table at NCBI.

If you blat the sequences against the correct genome build (e.g. hg19) you will get the sequence locations.

I have done this already. Further, I wish to perform enrichment analysis using gprofiler but IDs like XLOC_000236 are not recognised. On performing blast, I get more than 1 similar sequence so I cannot find the correct gene ID required for enrichment.
