windows installation

[xcarmengrandix]

Hi,

I'm trying to use tailfindr for the analysis of my Nanopore sequencing data. The analysis runs withour errors but returns an empty csv file.
I assume the problem is the same one reported here: adnaniazi/tailfindr#12

However, following the instructions on windows using "set HDF5_PLUGIN_PATH = /mypath/" doesn't work. How can I solve this? Am I missing something in the installation?

Thanks in advance for your help.

Hi @xcarmengrandix ,

To assist with your issue we would need more information.

What OS ae you running? and can you read the hdf files using a tool like hdfview or h5py on your platform?

Which version and architecture of the plugin have you installed on your platform?

Thanks,

Hi George,

I'm using Windows 10 64-bit and the VBZ version I installed is the following: https://github.com/nanoporetech/vbz_compression/releases/download/1.0.2/ont-vbz-hdf-plugin-1.0.2-win64.msi

I installed hdfview and I cannot see any hdf file in the path of the plugin (which for me is :\Program Files\OxfordNanopore\ont-vbz-hdf-plugin\hdf5\lib\plugin). I really have no experience in this kind of things so I'm sorry if I'm not clear.

Thanks for your help!

You would not find an hdf file in the path of the plugin - you should use hdfview to open onr of your experimental fast5 files once the plugin is installed.

The location where the plugin should be installed is: C:/ProgramData/hdf5/lib/plugin - can you confirm the contents of this directory?

Sorry for this, I checked in the fast5 folder of my experiment and I cannot see any file.

The location where the plugin should be installed is: C:/ProgramData/ can you confirm the contents of this directory?

In that directory I have the following files: vbz_hdf_plugin.dll and vbz_hdf_plugin.lib

If you dont have a fast5 file to open, then the vbz plugin cannot be failing - what data/process are you trying to execute? what does it consume as input?

Thanks,

Hi George,

I do have fast5 files in the folder, as you can see:

but if I access the folder with hdfview it looks empty. I'm afraid the problem comes from an error in the installation of the HDF5 Windows libraries, I'm trying to fix it now so let's see if that will solve the problem.

Thank you,
Carmen
