# Transferring Demultiplexed FASTQ 1. Demultiplexed FASTQ files should be put in a structure format as presented in the figure below. ![image alt](https://hackmd.io/_uploads/HJ1x5Yl76.png "title" =360x320) 2. If FASTQ files are uploaded, the sample ID should be the same as the name of relevant FASTQ. ![image.png](https://hackmd.io/_uploads/rJ2unKlma.png) ![image.png](https://hackmd.io/_uploads/ryKHhFgXa.png) For example, if my uploaded fastq was called ==23C00181-2==_S2_R*_001.fastq.gz like the figure above, and I inputed the sample ID called ==23C00181_2B==, which is different from my fastq, the analysis was finally failed.
