 These steps should set up an environment to perform single cell analysis with the tutorial workflow on a Linux system. Please note that we have encountered issues with conda environments on Mac OS. When using Mac OS we recommend installing the packages without conda using separately installed `python` and `R` versions. Alternatively, you can try using the base conda environment and installing all packages as described in the `conda_env_instructions_for_mac.txt` file. In the base environment, R should be able to find the relevant gsl libraries, so `LDFLAGS` and `CFLAGS` should not need to be set.

+# Troubleshooting
+
+## MulticoreTSNE
+A current workaround (as of 23/09/2022) to install `MulticoreTSNE` is to clone the `git` repository, adjust the `setup.py` and install manually as follows (solution provided by [Lisa Barros](https://github.com/lisa-sousa)):
+
+```
+git clone https://github.com/DmitryUlyanov/Multicore-TSNE.git
+```
+Then open the `setup.py` and replace `self.cmake_args or "--",` by `self.cmake_args or "",`. 
+
+Then install via
+```
+python setup.py install
+```
