For an external source, now OpenSeadragon seems to be unable to read the tiles

[katjaq]

It's a specific dataset which we get from an external source and need to slightly convert the way they provide the tiles so that MicroDraw can show them. Recently, the brain does not show up anymore. The error message : No TileSource was able to open undefined [object Object] (from tilesource.js which is probably inside OpenSeadragon). I am not sure why the error now.
