2 | Welcome to the 'ARB' Sequence Database Tools |

---|
4 | /*********** System Requirements *************/ |
---|
5 | |
---|
6 | ARB is currently developed on Linux PCs only. |
---|
7 | |
---|
8 | Compiling ARB using the gcc compiler (versions 2.95.3, 3.x and 4.x series) |
---|
9 | as well works on Mac OSX and Sun OS - but we do not publish or support |
---|
10 | these versions. |
---|
11 | |
---|
12 | |
---|
13 | Hardware Requirements (Linux): |
---|
14 | |
---|
15 | Good We use |
---|
16 | Real memory : 1 Gb 4 Gb |
---|
17 | Free discspace : 1 Gb more |
---|
18 | Computer speed : 2 GHz Cpu 2 GHz Dual Cpu |
---|
19 | |
---|
20 | |
---|
21 | Note : Memory is more important than a fast processor! |
---|
22 | |

24 | /*********** Files needed to install ARB *************/ |
---|
25 | |
---|
26 | File |
---|
27 | |
---|
28 | 'arb_install.sh' // install script |
---|
29 | 'arb.tgz' // ARB program |
---|
30 | 'zcat' // decompress (gzip) |
---|
31 | |
---|
32 | Note: do not uncompress and untar arb.tar.gz directly, |
---|
33 | use the install script !!! |
---|
34 | |
---|
35 | /*********** Install/Update ARB *************/ |
---|
36 | |
---|
37 | ARB consists of more than 750 files which are installed into a single |
---|
38 | directory. Creating this directory, copying all data into it, and setting |
---|
39 | the permissions correctly is done by the installation script |
---|
40 | |
---|
41 | 'arb_install' |
---|
42 | |
---|
43 | Goto the directory, where the files |
---|
44 | |
---|
45 | 'arb_install.sh' //install script |
---|
46 | 'arb_README.txt' //this file |
---|
47 | 'arb.tgz' //all the libs and bin |
---|
48 | 'zcat' //decompress |
---|
49 | |
---|
50 | are located and type '/bin/sh arb_install.sh' |
---|
51 | |
---|
52 | Answer all questions asked by the script. |
---|
53 | |
---|
54 | Notes:- The script will ask about a pt_server directory. This is a |
---|
55 | directory where arb will store big index files. |
---|
56 | You should enter a different path as you do not want to |
---|
57 | recreate those files after an ARB update. |
---|
58 | - Normally pressing enter will be a good choice. |
---|
59 | - You can rerun the script many times, it can be used to |
---|
60 | change an existing installation. |
---|
61 | |
---|
62 | Change your .cshrc/.profile files: |
---|
63 | |
---|
64 | Set the enviroment variable ARBHOME |
---|
65 | to the ARB installation directory |
---|
66 | Append $ARBHOME/bin to your PATH |
---|
67 | |
---|
68 | reread it, (logout+login ) |
---|
69 | |
---|
70 | goto a directory with a demo database 'eg demo.arb' |
---|
71 | and start 'ARB' with |
---|
72 | |
---|
73 | 'arb' |
---|
74 | |
---|
75 | /*********** Additional information *************/ |
---|
76 | |
---|
77 | * See arb_INSTALL.txt for additional software needed and/or useful |
---|
78 | together with ARB. |
---|
79 | |
---|
80 | |
---|
81 | /*********** PT_server *************/ |
---|
82 | |
---|
83 | To Install 'ARB' you have to know that some modules use a so |
---|
84 | called 'pt_server' (prefix tree server). |
---|
85 | |
---|
86 | ARB needs a writeable directory to store the pt_server files. |
---|
87 | Those files are needed for fast database search |
---|
88 | (by probe_design, probe_match and the automatic aligner) |
---|
89 | and need a lot of disc space (up to several 100 mega bytes, |
---|
90 | e.g. 4000 16S RNA sequences require about 40 MB). |
---|
91 | This files are not created now. They can be build by any user via |
---|
92 | <ARB_NTREE/Probes/PT_SERVER admin/Build server> |
---|
93 | You may define a special directory as the pt_server files location. |
---|
94 | This prevents any loss of data installing a new version of |
---|
95 | ARB. |
---|
96 | To minimize the use of ressources in a workstation cluster |
---|
97 | only one pt_server for each database is started on a user defined |
---|
98 | host. The first user starts the pt_server, and all other users |
---|
99 | can connect to it. |
---|
100 | |
---|
101 | /*********** What you should know: Swap *************/ |
---|
102 | |
---|
103 | Arb needs a lot of virtual memory |
---|
104 | (about 50 Mbyte for 5000 Sequences, Length = 3000). |
---|
105 | You can find out about installed swap space by typing: |
---|
106 | |
---|
107 | Linux 'top' |
---|
108 | SunOS 1.x: 'pstat -s' |
---|
109 | System V / SGI 'swap -s' |
---|
110 | OSF 'swapon -sv' |
---|
111 | |
---|
112 | Call your system administrator or local guru to increase your |
---|
113 | swap. (If you don't have such a nice person, try to read the |
---|
114 | man pages: 'man -k swap') |
---|
115 | |
---|
116 | |
---|
117 | /************* The Database ************/ |
---|
118 | |
---|
119 | In the current release a small dataset (demo.arb) is provided. |
---|
120 | This database contains a selection of artificial and real-life |
---|
121 | sequences. |
---|
122 | |
---|
123 | The intention of providing this small dataset first is to give |
---|
124 | you the opportunity to get familiar with the program and to |
---|
125 | test the performance of your computer system as well as the |
---|
126 | stability of ARB on your system. |
---|
127 | |
---|
128 | |
---|
129 | /*********** Bugs *************/ |
---|
130 | |
---|
131 | ARB is running properly and stably on our systems. However, it |
---|
132 | may be that there are bugs never detected by us or never |
---|
133 | appearing on our systems. Please don't hesitate to inform us |
---|
134 | about any bugs. A detailed description of the steps performed |
---|
135 | before the problem was evident and of the number and types of |
---|
136 | modules running at the same time would extremely be helpful to |
---|
137 | our computer scientists. |
---|
138 | |
---|
139 | Please report bugs into our bug tracker at |
