The 'zsync' files of databases file might be incorrect.

[NirvanaCh7]

I'm sorry for submitting an issue here.
I tried to download these databases using zsync.

https://resources.aertslab.org/cistarget/databases/homo_sapiens/hg38/screen/mc_v10_clust/region_based/hg38_screen_v10_clust.regions_vs_motifs.scores.feather

Pay attention to the SHA-1 checksum.

As you can see, its SHA-1 value matches the one recorded in the 'zsync' file's header, but differs from the one recorded in 'sha1sum.txt'.

I hope it's not my fault, as redownloading is a bit of a hassle.

So the ’zsync‘ files is incorrect.

I fixed it using ‘curl -C -’

It looks like it's working now.

To summarize,

the 'zsync' files are incorrect

Best wishes

[ghuls]

zsync files are removed for now as zsync was having issues with big files (larger than 2G) for a long time.

Looks like the zsync2 bug:
AppImageCommunity/zsync2#31
might finally be resolved in a fork of zsync2: NiLuJe/zsync2@a8e2d68
