summarizeToGene from tximeta: not all 'rnames' found or unique.

I'm running the RNA-seq gene-level workflow largely described by Mike Love ( It had been running just fine, but yesterday the workflow stopped and summarizeToGene with the following error:

"rnames' exact pattern
  is not unique; use 'bfcquery()' to see matches.Error in bfcrpath(bfc, txdbName) : not all 'rnames' found or unique."

This is after a fresh retrieval of metadata by tximeta. As I said - this had not caused any problems until yesterday, but I can't seem to solve it even after removing rids from the bfc cache.

Any thoughts? a paste from the .Rmd file is below:

```{r setup, include=FALSE} knitr::opts_chunk$set(echo = TRUE) library(tximeta) library(DESeq2) library(tidyverse) library("pheatmap") library("RColorBrewer") library("PoiClaClu") library("") library(BiocFileCache)

## RNA-seq analysis in G9a KO mice

## Trimmed the reads using TrimGalore!

`trim_galore -o Sample-2 Sample-2/Sample-2_1.fq.gz`

This probably isn't 100% necessary, as the reads are single and short, but did it anyway.

## Quantifying counts

I'll use Salmon (v 1.3.0) to make count table (

Downloaded transcriptome in fasta format from ensembl (

As well as the gene structures in GTF format (

The first step - index the transcriptome:
`salmon index -t Mus_musculus.GRCm38.cdna.all.fa -i GRCm38_index`

The map the reads:
for fn in Sample-{1..12};
samp=`basename ${fn}`
echo "Processing sample ${samp}"
salmon quant -i GRCm38_index  -l A \
        -r ${samp}/${samp}_1_trimmed.fq.gz \
        -p 4 --validateMappings --seqBias --gcBias --numBootstraps 50 -o quants/${samp}_quant

## Import data into R

We'll use tximeta.

files <- file.path("quants", paste0("Sample-", 1:12, "_quant"), "quant.sf")
names <- paste0("Sample_", 1:12)
cell <- factor(c("wt", "wt", "wt", "wt", "wt", "wt", "K182R", "K182R", "K182R", "K182R", "K182R", "K182R"), levels = c("wt","K182R"))
treat <- factor(c("PBS", "PBS", "PBS", "dex", "dex", "dex", "PBS", "PBS", "PBS", "dex", "dex", "dex"), levels = c("PBS", "dex"))
coldata <- tibble(files, names, cell, treat)

tximeta needs a BiocFileCache directory to access and save TxDb objects.
Do you wish to use the default directory: '/home/dweebis/.cache/BiocFileCache'?
If not, a temporary directory that is specific to this R session will be used.

You can always change this directory later by running: setTximetaBFC()
Or enter [0] to exit and set this directory manually now.
This location can also be set by environmental variable TXIMETA_HUB_CACHE.

I face the same issue. I do not have a solution, but a workaround. It is certainly a terrible idea and nobody should do it. It will also be overwritten by a future tximeta update.

That said, find your R library path/tximeta/extdata/hashtable.csv

Line 63 holds the information for the ENSEMBL GRCm38 genome, release 102. It has the same SHA256 checksum as the 101 release (and the 100 release, as well; I do not know if that is relevant). You performed your Salmon quantification with the release 101 (as did I), so my best guess is that these get mixed up somehow, but I have no idea about the specifics. Deleting that line allowed my pipeline to run as it did previously.

Good luck!

Thanks for the reply! That does seem like something I shouldn't do...but I may try it if I can't find a way to do it without editing tximeta.

Maybe this is more appropriate as a BiocFileCache issue?

Dear Miles,

Thanks for the bug report and sorry for the delay in response. This skipped my inbox for some reason.

Can you show me:

bfc <- BiocFileCache() (bfcquery(bfc, "Mus_musculus.GRCm38.102.gtf.gz") )
Entering edit mode

I've quantified some mouse data on my end with Ensembl release 102, and I was able to reproduce the bug wherein two entries are stored in the BFC, which leads to this error. This shouldn't ever happen under normal usage so the error was a good thing for helping catch the problem. Tximeta shouldn't add a database to the BFC if it already exists there with the same name.

I'll work on this today.

Entering edit mode

I've hopefully fixed this in v1.9.3 and v1.8.3 with this commit.

Duplicate entries were being added to the BFC because of a bug in how I was checking cases, introduced in the current release.

In ~2 days this code will be available via BiocManager::install, or you can test it immediately with install_github("mikelove/tximeta") (at the moment, release and devel branch are the same so this shouldn't break anything).

You will need to bfcremove the rids associated with Mus_musculus.GRCm38.102.gtf.gz before trying the new code. You can bfcquery as above and then do, e.g.:

bfcremove(bfc, c("BFC123","BFC234"))
Entering edit mode

Fantastic - thanks for the help, and I'll report back!

Entering edit mode

I update to tximeta from your gitthub, removed previous rids, and everything is running smoothly again. Thanks!

Sorry for the delay - I'm also not getting email notification of a comment. You've answered this below - but here's the output:
