Hello, I tried to download ROSMAP brain syn21589959 Fastq files using synapse get command. 52 out of 698 files could not be downloaded. Last year all 698 files were downloaded ok but were deleted. Both batch and single download failed. Error as following: synapse get syn21598674 Downloading [############--------]60.05% 2.0GB/3.3GB (58.3MB/s) RISK_71_S82_R2_001.fastq.gz.synapse_download_75349613 ValueError: Failed downloading syn21598674 to /RawData/RISK_71_S82_R2_001.fastq.gz.synapse_download_75349613 caused by SynapseError: Could not download the file: RISK_71_S82_R2_001.fastq.gz, please try again. Any clue what's the problem and how can I download the 52 files? Thank you for the help! Best, Chunling

The synapse client v2.5.1 worked for me, although it took 2 runs to download all 698 Fastq files. Thank you so much for the help! Best, Chunling
Hm, there is a patch release version of the client 2.5.1 that fixed some bugs in 2.5.0, but I can't think why you would be able to download some files but not others if that was the issue. Using python 3.9.6 and synapseclient 2.5.1, I was able to download the file you linked in the question, so I can't reproduce your error. My suggestions are to try: 1. Upgrade the synapse client to 2.5.1 using `pip install --upgrade synapseclient` 2. There is an issue with with argparse for python 3.9.8 which will break the synapseclient, so if you are using python 3.9.8 you could try updating to 3.9.9 3. If it still won't download, ask in the main [Synapse discussion forum](https://www.synapse.org/#!SynapseForum:default), where our Platforms team will be able to give you more detailed advice Sorry this isn't working for you!
I used Synapseclient v2.5.0. Thanks! Chunling
Hi Chunling, what version of the synapse client are you using?
