Hi Benjamin,
could you try to convert GFF3 to the GTF with gffread, and rerun STAR genome generation, and also the Salmon fasta generation with the GTF file? GFF3 sometimes produces inconsistent results.
Cheers Alex
Hi Alex Sorry for the delay they are performing maintenance on our supercomputer. I will get to this next week. Ben
i had the same problem running the bcbio_nextgen "RNA-seq" pipeline using STAR version STAR_2.6.1d where i explicitly used a gtf file created by bcbio to go with the BDGP6 fruit fly genome:

Since these are non-standard fasta/gtf, we will to isolate the problem. Please create fasta/gtf from just the transcript in question, and run STAR genome generation and mapping. Then we can check the header of the SAM file to see if the length of the transcript is correct.
Hello everyone!
In bcbio we solved it by generating ref-transcripts.full.fa out of the genome reference and ref-transcripts.gtf in genome/Celegans/WBCel235 in our case by using gffread (it was also a custom genome). It indeed gives longer sequences per transcript and is compatible with STAR transcriptome alignments. https://github.com/bcbio/bcbio-nextgen/issues/3671

This is the same with Tick genome from NCBI Genome ASM1692078v2

Good afternoon everyone,
I am new to bioinformatics and lately I have been encountering the same issue, but I only find discussions about it here and in the publications cited by you.
I am using the complete reference genome GRCh38.p14 to map with STAR and then I intend to quantify with Salmon, as I need TPM values.
The problem arises when I use Salmon, it presents the same error mentioned by others, and I identified that for some reason during the creation of the STAR index, it makes this cut.
I tried using the argument "--clipAdapterType None" during mapping, thinking it might be the solution, but it indicates that it does not exist, even though the manual says otherwise.
Could someone explain to me how to adjust this error better? If you need more information, just let me know.
Hi @marciow0205
I could not reproduce this problem. If you can isolate the "chromosome" which causes it, I could look into it.
Hi Alex,
We are experiencing the same problem when using the nf-core rnaseq pipeline (version 3.14.0). There seems to be an incompatibility between the indexing done with STAR and the transcript fasta files. One difference that I am seeing is that the length for us is not off by just one or two bases, but by a factor of two. Of note, the nf-core pipeline offers the choice of aligner to be either star_rsem or star_salmon. This issue occurs with BOTH choices, indicating that the issue is related to STAR and not either RSEM or SALMON. Could you have a look at this problem as STAR is an excellent aligner and the quantification from RSEM and SALMON are very useful. Below I provide some details of the pipeline for your consideration: 1)GTF file is entered or created from GFF file 2) Transcripts are extracted from the reference genome 3) GTF is filtered to ensure that only entries that match the transciptome are included 4) STAR index is done on these files 5) Salmon quant is run using the transciptome aligned bam from STAR in alignment mode

SAM file says target gene1 has length 2840, but the FASTA file contains a sequence of length [1420 or 1419]
UPDATE
Hi to all who have been experiencing this problem.
I have looked into it a bit and have discovered that in all cases the root cause appears to be a malformed GFF file. Since most of the work we do involves non model organisms, the quality of the annotations is always an issue. The work-around for this particular problem was to not only validate the GFF files, but actually repair them. The solution involves passing the GFF file to multiple programs:
agat_convert_sp_gxf2gxf.pl | gt gff3 | gffread
Doing this resolved the issue for us.
I will re-iterate: Having a "validated" GFF file is NOT sufficient for these indexing problems.
Hope this information helps :-)
Good morning 😊 I am opening this issue on the recommendation of @rob-p and our discussion over on BioStar (https://www.biostars.org/p/486346/#486637).
I was using STAR to index and align my raw reads to the available genome I have. This was done successfully but then using salmon to quantify I received the following error (please note salmon transcriptome was generated using gffread on the same files used for input for STAR indexing).
"SAM file says target evm.model.Sc0a5M3_402_HRSCAF_756.4.1.5f5b2bc4 has length 536, but the FASTA file contains a sequence of length [538 or 537]"
I then just ran salmon in index and alignment mode and this error was not thrown, but quantification successfully processed.
On closer inspection it seems that the indexing stage with STAR is causing the differing lengths of 23 transcripts by 1 or 2 bases and I have absolutely no idea why this is (link to image of transcripts - https://ibb.co/r591n3n). This was done by the following comparisons of the transcript lengths.
Please find below the STAR index script, as well as the alignment script I used. Please let me know if you need anymore information, I have tried to follow best practices but this is my first issue submission 😊
