Thanks for the tximport package, I'm hardcore biologist doing PhD in genomics, it so frustrating for me to use R for data analysis work. That too working with non-model organisms no one had heard of before. After de novo assembly step I used salmon for quantification and generated the quant.sf files for 30 datasets. I used trinity abundance matrix generator scripts to generate gene counts.matrix for all the samples. How do I combine all the matrices into a single matrix which I'll be fed into DESeq2/EdgeR packages. The organism I'm working for doesn't have any information in the public domain. I'm facing an error while loading samples.txt file, saying the matrix is not correct. Please find the sample.info file.

The support site is for specific software questions, if you find an error with a particular package, provide the error, your code and tag the relevant package. Here you've tagged edgeR and DESeq2 which are developed by different maintainers, and then the support site emailed both development teams, yet you haven't provided the error or the code you used. I'd suggest making a new post where you tag the relevant package, and provide the error and the code.
