22 | Files needed to install ARB |
---|
23 | --------------------------- |
---|
24 | |
---|
25 | File |
---|
26 | |
---|
27 | 'arb_install.sh' // install script |
---|
28 | 'arb-*.tgz' // ARB program |
---|
29 | |
---|
30 | |
---|
31 | Available ARB versions: |
---|
32 | |
---|
33 | arb-*.centos5-amd64.tgz |
---|
34 | arb-*.centos6-amd64.tgz |
---|
35 | arb-*.ubuntu1004-amd64.tgz |
---|
36 | arb-*.ubuntu1204-amd64.tgz |
---|
37 | arb-*.ubuntu1304-amd64.tgz |
---|
38 | arb-*.osx.tgz |
---|
39 | |
---|
40 | You need exactly ONE of the available 'arb-*.tgz'! |
---|
41 | |
---|
42 | Notes: |
---|
43 | |
---|
44 | * all versions are 64bit versions |
---|
45 | (if you really need a 32bit version, see http://download.arb-home.de/release/arb_5.5/) |
---|
46 | |
---|
47 | * all versions are compiled without OPENGL |
---|
48 | (if you rely on OPENGL features, either stick with arb_5.5 or compile arb from source) |
---|
49 | |
---|
50 | * OSX version is available as arb-*.osx.tgz |
---|
51 | and via MacPorts (see arb_OS_X_MacPorts.txt included inside arb-*.osx.tgz) |
---|
52 | |
---|
53 | * debian users should either use the arb package in 'non-free' or |
---|
54 | install one of the centos versions (see also arb_INSTALL.txt) |
---|
55 | |
---|
56 | |
---|
57 | Install/Update ARB |
---|
58 | ------------------ |
---|
59 | |
---|
60 | ARB consists of more than 1400 files which are installed into a single |
---|
61 | directory. Creating this directory, copying all data into it, and setting |
---|
62 | the permissions correctly is done by the installation script |
---|
63 | |
---|
64 | 'arb_install.sh' |
---|
65 | |
---|
66 | Open a terminal, change to the directory where you have saved the |
---|
67 | files needed for installation: |
---|
68 | |
---|
69 | 'arb_install.sh' // install script |
---|
70 | 'arb_README.txt' // this file |
---|
71 | 'arb-*.tgz' // your chosen ARB version |
---|
72 | |
---|
73 | |
---|
74 | and type |
---|
75 | |
---|
76 | '/bin/sh arb_install.sh' |
---|
77 | |
---|
78 | (to install arb for all users call the script as root or via sudo) |
---|
79 | |
---|
80 | |
---|
81 | Answer all questions asked by the script. |
---|
82 | |
---|
83 | Notes:- The script will ask about a pt_server directory. This is a |
---|
84 | directory where arb will store big index files. |
---|
85 | You should enter a different path as you do not want to |
---|
86 | recreate those files after an ARB update. |
---|
87 | - Normally pressing enter will be a good choice. |
---|
88 | - You can rerun the script many times, it can be used to |
---|
89 | change an existing installation. |
---|
90 | |
---|
91 | Change your .cshrc/.profile files: |
---|
92 | |
---|
93 | Set the environment variable ARBHOME |
---|
94 | to the ARB installation directory |
---|
95 | Append $ARBHOME/bin to your PATH |
---|
96 | |
---|
97 | reread it, (logout+login) |
---|
98 | |
---|
99 | goto a directory with a demo database 'eg demo.arb' |
---|
100 | and start 'ARB' with |
---|
101 | |
---|
102 | 'arb' |
---|
103 | |
---|
104 | Compile ARB from source |
---|
105 | ----------------------- |
---|
106 | |
---|
107 | * See arb_INSTALL.txt for information about how to compile |
---|
108 | arb from source. |
---|
109 | |
---|
110 | |
---|
111 | Additional information |
---|
112 | ---------------------- |
---|
113 | |
---|
114 | * See arb_INSTALL.txt for additional software needed and/or useful |
---|
115 | together with ARB. |
---|
116 | |
---|
117 | |
---|
118 | PT_server |
---|
119 | --------- |
---|
120 | |
---|
121 | To Install 'ARB' you have to know that some modules use a so |
---|
122 | called 'pt_server' (prefix tree server). |
---|
123 | |
---|
124 | ARB needs a writeable directory to store the pt_server files. |
---|
125 | Those files are needed for fast database search |
---|
126 | (by probe_design, probe_match and the automatic aligner) |
---|
127 | and need a lot of disc space (up to several 100 mega bytes, |
---|
128 | e.g. 4000 16S RNA sequences require about 40 MB). |
---|
129 | This files are not created now. They can be build by any user via |
---|
130 | <ARB_NTREE/Probes/PT_SERVER admin/Build server> |
---|
131 | You may define a special directory as the pt_server files location. |
---|
132 | This prevents any loss of data installing a new version of |
---|
133 | ARB. |
---|
134 | To minimize the use of ressources in a workstation cluster |
---|
135 | only one pt_server for each database is started on a user defined |
---|
136 | host. The first user starts the pt_server, and all other users |
---|
137 | can connect to it. |
---|
138 | |
---|
139 | |
---|
140 | What you should know: Swap |
---|
141 | -------------------------- |
---|
142 | |
---|
143 | Arb needs a lot of virtual memory |
---|
144 | (about 50 Mbyte for 5000 Sequences, Length = 3000). |
---|
145 | You can find out about installed swap space by typing: |
---|
146 | |
---|
147 | Linux 'top' |
---|
148 | SunOS 1.x: 'pstat -s' |
---|
149 | System V / SGI 'swap -s' |
---|
150 | OSF 'swapon -sv' |
---|
151 | |
---|
152 | Call your system administrator or local guru to increase your |
---|
153 | swap. (If you don't have such a nice person, try to read the |
---|
154 | man pages: 'man -k swap') |
---|
155 | |
---|
156 | |
---|
157 | The Database |
---|
158 | ------------ |
---|
159 | |
---|
160 | In the current release a small dataset (demo.arb) is provided. |
---|
161 | This database contains a selection of artificial and real-life |
---|
162 | sequences. |
---|
163 | |
---|
164 | The intention of providing this small dataset first is to give |
---|
165 | you the opportunity to get familiar with the program and to |
---|
166 | test the performance of your computer system as well as the |
---|
167 | stability of ARB on your system. |
---|

---|
170 | Bugs |

171 | ---- |
---|
172 | |
---|
173 | ARB is running properly and stably on our systems. However, it |
---|
174 | may be that there are bugs never detected by us or never |
---|
175 | appearing on our systems. Please don't hesitate to inform us |
---|
176 | about any bugs. A detailed description of the steps performed |
---|
177 | before the problem was evident and of the number and types of |
---|
178 | modules running at the same time would be extremely helpful to |
---|
179 | our computer scientists. |
---|
