I'm trying to construct the reference for Salmon, but the process stopped with this error:

the commandis:

salmon index -t CRCH38_and_decoys.fa.gz -d decoys.txt -i GRCh38_salmon_index --gencode

the last part of the error is:

[2024-02-19 12:14:55.227] [puff::index::jointLog] [warning] Entry with header [ENST00000634174.1|ENSG00000282732.1|OTTHUMG00000191398.1|OTTHUMT00000487783.1|ENST00000634174|ENSG00000282732|28|unprocessed_pseudogene|], had length less than equal to the k-mer length of 31 (perhaps after poly-A clipping)

it could be a problem of CPU memory?

Thanks
