How to design KASP primers for LGC:

   All KASP primers generally have a minimum length of 20 base pairs, some primers however may have to be longer depending on  whether it meets the algorithms assay design criteria.

   We can only incorporate a maximum of 1 degenerate bases per sequence

   The recommended maximum distance between the common and reverse primers is about 80 base pairs.

   The only IUPAC codes that we can accept for assay design is M,R,W,S,Y and K

How to install tensorflow with GPU support on windows:

Update NVIDIA driver
Install Visual Studio https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=Community&rel=16
Restart computer
Install cuda toolkit https://developer.nvidia.com/cuda-downloads. (NB. It's possible this step (and steps 2-3) may not be necessary. See below)
Install Anaconda
Go to the "Start menu" find the "Anaconda3" item and then click on the "Anaconda Powershell Prompt"
Run:

conda update conda
conda update anaconda
conda update python
conda update --all
conda create --name tf-gpu
#Now exit from the Powershell you are using and then open a new one before you activate the new "env".
conda activate tf-gpu
#NB. the line below appears to install cuda in addition to cudnn. Perhaps the windows installation is required to add the cuda paths. That could probably be done manually. You can manualy edit the path in Windows by typing 'path' in the start menu and selecting editing the system environmental variables.
conda install -c conda-forge cudnn
conda install pip
pip install --upgrade pip  --user
pip install --upgrade tensorflow --user
conda install ipykernel jupyter
#below is optional
conda install -c anaconda tensorboard
python -m ipykernel install --user --name tf-gpu --display-name "TensorFlow2-GPU"
jupyter notebook

In the Jupyter Notebook create a cell with the following contents and run to check that a GPU is listed in the physical devices:

import tensorflow as tf
tf.config.list_physical_devices()

Try running the MNIST hand written digits example in a Jupyter notebook as described at https://www.pugetsystems.com/labs/hpc/How-to-Install-TensorFlow-with-GPU-Support-on-Windows-10-Without-Installing-CUDA-UPDATED-1419/

How to transfer files to/from HPC tape storage:

#To recall a file from tape you must have read access.
#dmget /apollo/dir1/dir2/file
#To migrate a file to tape and keep it on disk (i.e. dual state, state=DUL). You must have write access to file to migrate it.
#dmput /apollo/dir1/dir2/file
#To migrate a file to tape and remove it's disk blocks (i.e. offline, state=OFL)
#dmput -r /apollo/dir1/dir2/file
#To get detailed information about file's attributes.
#dmattr /apollo/dir1/dir2/file
#To determine a file's state, three letter code will be returned. States are listed below.
#dmattr -a state /apollo/dir1/dir2/file
#To determine a file's sitetag.
#dmattr -a sitetag /apollo/dir1/dir2/file
#To prevent file(s) being migrated to tape, set the sitetag to 16.
#dmtag -t 16 /apollo/dir1/dir2/file1 /apollo/dir1/dir2/file2
#alternatively:
#dmfind /apollo/dir/files | dmtag -t 16
#To allow file(s) to migrate to tape, set the sitetag back to 0.
#dmtag -t 0 /apollo/dir1/dir2/file1 /apollo/dir1/dir2/file2
