I'm looking for raw human ngs data to practice in bioinformatics. Better if it is from different machines (illumina, roche, pacsbio, etc). Panels, exomes and genomes. Anyone knows something?
At least PacBio do provide some example datasets on their DevNet resource. You should be able to get a lot of different Illumina data from the public data in BaseSpace. I am not sure where to look for official samples from Roche 454, but I wouldn't bother too much as it is discontinued anyway. Rather go for MinIon or IonTorrent data, if you want more.
