Install directions¶

The computer performing the tomographic reconstruction must have CUDA/GPU installed. tomostream consists of two modules TomoScanApp and tomostream tools.

TomoScanApp¶

Provides all the EPICS PVs needed by tomostream. To install TomoScanApp follow these steps:

Build a minimal synApps¶

To build a minimal synApp:

$ mkdir ~/epics
$ cd epics

Download in ~/epics assemble_synApps.sh
Edit the assemble_synApps.sh script as follows:
- Set FULL_CLONE=True
- Set EPICS_BASE to point to the location of EPICS base. This could be on APSshare (the default), or a local version you built.
- For tomostream you only need BUSY and AUTOSAVE. You can comment out all of the other modules (ALLENBRADLEY, ALIVE, etc.)
Run:
```
$ assemble_synApps.sh
```
This will create a synApps/ directory:
```
$ cd synApps/support/
```
Edit busy-R1-7-2/configure/RELEASE to comment out this line:
```
ASYN=$(SUPPORT)/asyn-4-32).
```

Clone the tomostream module into synApps/support:

$ git clone https://github.com/tomography/tomostream.git

Edit tomostream/configure/RELEASE to comment out this line:
```
ASYN=$(SUPPORT)/asyn-4-38
```
Edit tomostream/tomoStreamApp/src/Makefile to comment out this line:
```
tomoStreamApp_LIBS += asyn
```
Edit configure/RELEASE add this line to the end:
```
TOMOSTREAM=$(SUPPORT)/tomostream
```
Edit Makefile add this line to the end of the MODULE_LIST:
```
MODULE_LIST += TOMOSTREAM
```
Run the following commands:
```
$ make release
$ make -sj
```

Testing the installation¶

Edit /epics/synApps/support/tomostream/configure
- Set EPICS_BASE to point to the location of EPICS base:
- EPICS_BASE=/APSshare/epics/base-3.15.6

Start the epics ioc and associated medm screen with:

$ cd ~/epics/synApps/support/tomostream/iocBoot/iocTomoStream
$ start_IOC
$ start_medm

tomostream python tools¶

$ cd ~/epics/synApps/support/tomostream/
$ python setup.py install

Testing the installation¶

$ cd ~/epics/synApps/support/tomostream/iocBoot/iocTomoStream
$ python -i start_tomostream.py
