Is Single end RNAseq can use this version ? #343

Open Portulaca666 opened 10 months ago

OK . Thanks for great version turbo! My RNA-seq reads is from this Project —— PRJNA454873 I am not sure the single-end data can use your new turbo version .

Please help me !

You can run rMATS with -t single. Here's the description from the README: https://github.com/Xinglab/rmats-turbo/tree/v4.2.0#all-arguments

-t {paired,single}    Type of read used in the analysis: either "paired" for
                      paired-end data or "single" for single-end data.
                      Default: paired

See this post for a possible solution if some samples are paired-end and others are single-end: https://github.com/Xinglab/rmats-turbo/issues/180#issuecomment-1048064842

Hi ! I try to run in this way .this is my code `s1_path=/home/xjhuang_pkuhpc/gpfs1/help/LQQ/clean/trimed_fastq/ss1.fastq.csv

When I see each output .I found the USED reads is so little image What should I do ?

EricKutschera commented 10 months ago

Almost all of the alignments are either NOT_NH_1 or NOT_EXPECTED_READ_LENGTH:

NOT_NH_1: 420853115 (54%)
NOT_EXPECTED_READ_LENGTH: 349347110 (45%)
total: 774466429

The command you posted had: --readLength 50. Maybe the reads are not actually length 50. If the reads are not expected to be the same length you can use --variable-read-length: https://github.com/Xinglab/rmats-turbo/issues/83#issuecomment-766845772
