[maker-devel] Errors with Blast engine and Fasta index

[Ence,daniel]

Hi Isabel, The warning is referring to an empty entry in one of the fasta files (“Warning: Sequence contains no data”). This is probably in the genome fasta file that you are trying to annotate. Can you check the fasta entry “NODE_1_length_465927_cov_94.9908”?

Hello,

I am new to linux and bioinformatics but I managed to set MAKER (v2.31.9) running smoothly a few weeks ago and I could perform a de novo annotation of one of my genome. In the meantime, I worked on other topics and, yesterday, when I tried to annotate another genome, MAKER was not working.
The following message was appearing:

BLAST engine error: Warning: Sequence contains no data

ERROR: Failed while preparing masked sequence

I tried to solve the problem (re-install Repeatmasker and blast, check location of the several executables, check tmp folder, re-install MAKER, etc) but still, I am not able to solve the problem.
Could you please help me out with this? Thank you so much.

Cheers,
Isabel
