63 Now you can **allocate a node** for yourself, so you will have enough memory and power for your reconstruction.

72 You will get a node for 6 hours, you can also choose longer or shorter times.
73
74 It can take some time before you get a node, then it will tell you which node is reserved for you. (Example: max-exfl069)
75
76 \\
77
78 Now you can  **login via ssh** on this node:

80 (% class="code" %)
81 (((
82 ssh max-exfl069

84
85 Enter your password.

92
93 Hint: Please use partition=psx, if you use =all, the connection might close while you are working if someone with higher priority needs the node you are working on.
94
95 \\
96
97 Now you are on a different node [[image:http://confluence.desy.de/s/de_DE/7901/4635873c8e185dc5df37b4e2487dfbef570b5e2c/_/images/icons/emoticons/smile.svg||title="(Lächeln)" border="0" class="emoticon emoticon-smile"]].

101 You first have to **load the anaconda module:**
102
103 (% class="code" %)
104 (((
105 module load anaconda/3
106 \\
107 )))
108
109 and **activate your virtual environment**, depending on where you installed it:
110
111 (% class="code" %)
112 (((
113 source activate ~~/envs/tomopy
114 )))
115
116 \\
117
118 ~~/ takes you back to your home directory. In this case, the environment "tomopy" was installed in the home directory in the folder "envs". 
119
120 \\
121
122 now you can **start spyder**:
123
124 (% class="code" %)
125 (((
126 spyder&
127 )))
128

134
135 \\
136
137 You can also start another terminal e.g. if you want to look at your data / reconstructions in fiji.
138

140
141 Hint: You can check your partition via
142
143 (% class="code" %)
144 (((
145 my-partitions
146 )))
147
148 You should have access to psx.
