Hi Sharma, I am adding a reply for future reference.
the main dashboard or browser window has filters on the left:
My Datasets is where your own datasets and uploaded samples are.
Datasets shared with me Are datasets a collaborator shared with you
Public Datasets are datasets that have been published in databases like GEO, TCGA, BroadInstitute, etc...
Community datasets are datasets other researchers have uploaded to InSilico DB and have made them available to everyone.
