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

71 You will get a node for 6 hours, you can also choose longer or shorter times.
72
73 It can take some time before you get a node, then it will tell you which node is reserved for you. (Example: max-exfl069)
74
75 \\
76
77 Now you can  **login via ssh** on this node:
78
79 (% class="code" %)
80 (((
81 ssh max-exfl069
82 )))
83
84 Enter your password.

91
92 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.
93
94 \\
95
96 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"]].

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

133
134 \\
135
136 You can also start another terminal e.g. if you want to look at your data / reconstructions in fiji.
137

139
140 Hint: You can check your partition via
141
142 (% class="code" %)
143 (((
144 my-partitions
145 )))
146
147 You should have access to psx.
