The URL should be: https://www.metaboanalyst.ca/MetaboAnalyst/resources/libs/kegg/metpa/mmu.qs. The issue is related to our recent update to address the issue with the “qs” R package - which was removed in the recent R release
Thank you for your reply, but I still found the same problem. The files downloaded from the two links “https://www.metaboanalyst.ca/resources/libs/kegg/metpa/mmu.qs” and "https://www.metaboanalyst.ca/MetaboAnalyst/resources/libs/kegg/metpa/mmu.q"s" are consistent. I still get an error when I execute the following code:
________________________________________________________________________
library(MetaboAnalystR)
Bioconductor version 3.12 (BiocManager 1.30.12), ?BiocManager::install for help
Bioconductor version ‘3.12’ is out-of-date; the current release version ‘3.23’
is available with R version ‘4.6’; see Bioconductor - Install
MetaboAnalystR 3.1.0 initialized Successfully
qs::qread(“/home/Metabolome/test_lxj/fankui/test/mmu.qs”)
Error in qs::qread(“/home/Metabolome/test_lxj/fankui/test/mmu.qs”) :
QS format not detected

The files downloaded before April 30, 2026, can be opened normally, so I was wondering if the update process did not consider users who still use qs. Can the files be read using qs2? I haven’t tried it yet because I haven’t successfully installed qs2 yet.
This should be the cause - MetaboAnalyst web is updated, MetaboAnalystR is not (there are 3 weeks delay)
Solution:
Use the web for now, or try to fix qs2 installation.
