Hi all. I´m using Kallisto with DeSeq2 to do a DGE analysis on my samples. I used the following commands:
kallisto index -i cro_kal_index $StringTieDir/merged_transcriptome.fasta //for each sample kallisto quant -i cro_kal_index -o mapping_to_genome/07_kallisto/idio_1 $DATA/R1_cut_paired.gz $DATA/R2_cut_paired.fastq.gz
DeSeq2 manual advises to use tximport to import the data files to downstream analysis However, I get this error:
Error in H5Fopen(file, "H5F_ACC_RDONLY", native = native) : HDF5. File accessibility. Unable to open file
My first approach was to use the tsv files instead of the h5 files. However, the same error still occurs.
The files were generated in a Linux server and transferred over by scp to Windows. I checked the md5 sums and everything seems fine. The thing that puzzles me the most is an error related to the rhdf5 library occurring with tsv files.
Below is my script with the session info:
library(tximport) library(rhdf5) files <- "abundance.h5" names(files) <- paste0("sample", 1) txi.kallisto <- tximport(files, type = "kallisto", txOut = TRUE) #Error in H5Fopen(file, "H5F_ACC_RDONLY", native = native) : #HDF5.

Yes, I have seen other users have a similar error, but I could not get a solution. If there is any post with the exact same error I have missed let me know.
