      I know it does not make sense to provide the full path, but that seems to work in many cases. Like the example I tried from your dataset above (even though I was in the directory where the file was located).

        We have also experienced these problems, and as a result always use a relative path to the file if we are in the directory already:

        Code:
        $ fastq-dump ./SRR1266967.sra

            Dear Kruger,

            Did it ran well for you? When I ran fastq-dump ./SRR1266967.sra, it failed immeditely where as for other files it ran for 3 seconds and throwed this error.

              I just tested it, and it actually works well with or without prepending './'. I am using fastq-dump version 2.3.5 by the way.

                  Hi

                  I am using fastqdump 2.1.7. I downloaded the sratoolkit.2.4.2-ubuntu64 and later installed it suing sudo agt-get command. Inside the bin folder of sratoolkit.2.4.2 I am able find following version fastq-dump version:

                  fastq-dump.2.4.2; fastq-dump; fastq-dump.2

                  But I am not able to run the fastq-dump.2.4.2. Not only this file but also all other files of version 2.4.2 were higlighted in green color and I am not able to run those highlighted in green color.

                  Please guide me.

                    This is why you don't need to re-invent sftp and gzip.

                    Just ... don't ... do it.

                      Do the following to make that fastq-dump executable in the bin folder of sratoolkit-2.4.2:

                      Code:
                      $ chmod u+x fastq-dump*
                      Hopefully this is the only version on your machine now. Just to be safe provide the full path to this new file when you try to run it and see if it works.

                        For curiosity I have also tried SRR1266967.sra and I could convert to fastq successfully. But notably, download of the the SRA file (about 430 Mb) was very slow and took about 30 minutes. Maybe you have downloaded the SRA file only partially?

                        Code:
                        wget ftp://ftp-trace.ncbi.nlm.nih.gov/sra/sra-instant/reads/ByRun/sra/SRR/SRR126/SRR1266967/SRR1266967.sra
                        md5sum SRR1266967.sra
                          01c653175917848a60ad01f700793a49  SRR1266967.sra
                        fastq-dump -F SRR1266967.sra
                        grep ^@ SRR1266967.fastq | wc
                          16557954 16557954 521453404
                        As expected I got 16557954 reads.

                          I had a similar error message. The problem in my case was that the temporary download directory was full. I resolved it by changing the download directory using vdb-config -i.

                          From: http://trace.ncbi.nlm.nih.gov/Traces..._doc&f=std#s-3

                          The default location for the "download repository" is:

                          Linux: /home/[user_name]/ncbi/public
                          Mac OS X: /Users/[user_name]/ncbi/public
                          Windows: C:\Users\[user_name]\ncbi\public

                          Here's hoping for some more helpful error messages in the next release!

                            by seqadmin


                            Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
