This is my first time analyzing RNA sequencing data for gene expression. I am trying to import count data from Kallisto to DESeq2 using the tximport package following the instructions here. After running this code:

filenames <- list.files("./Data", full.names = TRUE, pattern = "*abundance.h5")
files <- filenames %>% `names<-`(str_extract(filenames, "SWS[:digit:]*"))

txi.kallisto <- tximport(files, type = "kallisto", txOut = TRUE)

I get the following error:

Note: importing `abundance.h5` is typically faster than `abundance.tsv`

In addition: Warning message:
Unnamed `col_types` should have the same length as `col_names`. Using smaller of the two.

I'm trying to import the .h5 files, but when I peak in the .tsv files, they are formatted like this:

When I run the commands using the abundance.tsv files:

txdb <- makeTxDbFromGFF("gencode.vM20.annotation.gff3.gz") # Pulled this file from: https://www.gencodegenes.org/mouse/release_M20.html
k <- keys(txdb, keytype = "TXNAME")
tx2gene <- select(txdb, k, "GENEID", "TXNAME")
txi.kallisto.tsv <- tximport(files, type = "kallisto", tx2gene = tx2gene, ignoreAfterBar = TRUE)

It actually imports all my files, but renders the subsequent error:

Note: importing `abundance.h5` is typically faster than `abundance.tsv`
reading in files with read_tsv
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 
Error in summarizeToGene(txi, tx2gene, varReduce, ignoreTxVersion, ignoreAfterBar,  : 

  None of the transcripts in the quantification files are present
  in the first column of tx2gene. Check to see that you are using
  the same annotation for both.

Example IDs (file): [ENSMUST00000177564.1-Trdd2, ENSMUST00000196221.1-Trdd1, ENSMUST00000179664.1-Trdd1, ...]

Example IDs (tx2gene): [ENSMUST00000193812.1, ENSMUST00000082908.1, ENSMUST00000192857.1, ...]

  This can sometimes (not always) be fixed using 'ignoreTxVersion' or 'ignoreAfterBar'.

Thanks again!

tximport as is currently implemented assumes you don't modify the names of the output files of the methods. This is generally a good idea I think not to modify the filenames themselves, so I probably won't change this. There was a very recent post here showing some code to get around it, by specifying your own importer.
