It's probably in the header and there's likely no reason to do so. It'd help if you provided a bit more detail.

I'm running Qimme 2 for running cansava 1.8 the file name should be in the particular format for example L2S357_15_L001_R1_001.fastq.gz. The underscore-separated fields in this file name are the sample identifier, the barcode sequence or a barcode identifier, the lane number, the read number, and the set number.

I wrongly renamed the original file so i cant able to run my command.

In this example you appear to have lost the index sequence. It should be present in 1:N:0:4 in place where 4 is. I should look like 1:Y:18:ATCACG.

you have sample number (4) in place of index. By any chance, is this from base space v2? Refer to sample sheet from sequencing core for sample 4. manojkumarbioinfo.
