Troubleshooting

Common issues when converting raw volumes to the sharded binary format.

"Could not determine dimensions"

Specify dimensions explicitly:

bun scripts/decompose-volume.ts data.raw 512 512 256

Large volumes run out of memory

The script processes data in z-slabs to limit memory usage, but very large volumes may still require significant RAM. Ensure at least 8GB of free RAM.

16-bit normalization looks wrong

The script uses global min/max for normalization. If the volume has outliers, contrast may be compressed. Options:

1. Pre-process the raw data to adjust the value range
2. Use --native to keep the 16-bit data unconverted (stored internally as r16float, not bit-exact) and adjust contrast with windowing in the viewer
