    FTP transfer - corrupt files at other end

    Hello members,

    I've 218 genome (E. coli) files - 436 fastq.gz files.

    I created their symbolik links in one folder (as they are scattered over multiple sequencing folders and different depths of directory), and sent them using bash script via FTP utility.

    I do not get any error, warning or whatsoever during transfer. I can see their size at FTP web interface as in on command line interface on my end.

    But the data on the other end is corrupted.
    I'm unable to understand what might be causing this, and how should I fix this?

    Please guide.

    Did you set "binary on" ?

    You have to set "binary on" when using FTP.

      Hi Richard,
      Thanks for your reply.
      It by default says:

      Uploading in BINARY file XTGEN_20121130_SN180_IL100028322_TTGGTATG-FMC_UTI_01875_L004_R1_trimmed.fastq.gz

        What FTP program are you using? Some FTP programs can't follow soft-links correctly.

            Have you tried sftp instead of plain ftp?

              Hi,

              I cannot use CURL, stfp as the user name I've has already an @ in it, and thus, many command line transfer utilities refuse to accept it.

              something like:

              user@group_name

                Can you clarify what you are trying to do?

                Is this transfer between servers i.e. you have created a symlinked folder of files on server A that you are trying to get at from server B (via the web?).

                  Hi Genomax,
                  I created symlinks at remote server A.
                  Wrote bash script at Server A, with FTP which uses - password, username of Server B. This bash script loops over .fastq.gz files (which are symlinks here).

                  Folder:
                  -->has 436 symlinks..

                  From Server A fastq.gz -->FTP Server B

                  bash script.sh inside the symlinks folder.

                      Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
                      by SEQadmin2



                      Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

                      Cancer Drug Resistance: The Lingering Barrier to Rising Survival
                      by SEQadmin2



                      Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

                      There is no single reason why many patients don’t respond to treatment as expected. Cancer is...

                      Reply to Nine Things a Sample Prep Scientist Thinks About Before Sequencing
                      by GATTACAT
                      Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.
