• ssh
  Normally it is best to use ssh -X to allow X-applications to work.

  keeping connection via ssh:
  add to the $HOME/.ssh/config file
  host *
    ControlMaster auto
    ControlPath ~/.ssh/ssh_mux_%h_%p_%r
  Now you can open another terminal, and ssh and scp commands will not ask for the password.
  if you use mimer
  using something like: ssh -J teok-vve@mimer valera@idun
  will allow you to go immediately to your computer (especially nice with combination to
  the previous advice)

Backup of /home

There exist a default .profile in /etc/profile.
/teo/etc/profile

ex. scp. if I want to copy a file from embla to my directory on my local temp1 disk
scp2 -1 username@embla:/usr/people/username/filename /temp1/username/

ROOT 30/5-01

Stage I. Preparing the presentation

Prepare your presentation in ps or pdf format, Login to pc.teokem.lu.se (uid scanner)

convert t.pdf -size 1024x768 a%02d.jpg or
convert t.ps -size 1024x768 a%02d.jpg

To rotate portrait-oriented slides to landscape type

convert a*.jpg -rotate "90<" %02d.jpg
rm a*.jpg

(landscape pictures will be intact)

Stage II. Moving the presentation to memory stick

The card reader is plugged into the machine 'lage', in the same room where the Windows machine is (non smoking room).
Mount the card reader

mount /mnt/reader  No longer needed.
mkdir /mnt/reader/Ulf
cp *.jpg /mnt/reader/Ulf
umount /mnt/reader

Stage III. Performing the presentation

Plug the memory stick into the projector. Press the Menu button, navigate to the Picture Viewer mode. Navigate into your directory on the memory stick, come to the first slide, 'enter', select 'Full Screen'. Use cursor keys 'left' and 'right' on the remote control for navigation.

Stage IV. After the presentation

Hej på er

Här följer en samling blandade tips och tricks jag samlat på mig under åren här.
Program som nämns nedan är:
ps2eps
convert (imagemagick)
pdfjoin
openoffice
pymol
scribus
eps2eps

Rotera ps och konvertera till eps
ps2eps -f -R + -g -s a4 input.ps output.eps
bra för att ta hand om eps från gnuplot

Konvertera bilder till tiff med cmyk och LZW kompression - bästa format för publicering
convert filnamn -colorspace CMYK -compress LZW nyttfilnamn.tif

Sammanfoga flera pdf-filer till en enda i bestämd ordning och gör till a4 samtidigt
pdfjoin filnamn1 filnamn2 filnamn3 --fitpaper false --paper a4paper --outfile allt.pdf

Hur man skapar numrerade formler i Openoffice Writer
skriv "fn" först på en rad, tryck sedan F3.

kommandon för högupplöst bild för tryck i pymol (konverteras sedan lämpligen med convert till tiff)
ray 3000x4000 (eller nåt sånt)
png filnamn.png

gör alignment och beräkna rmsd av två strukturer av samma molekyl i pymol
skriv följande kommande med de residue ids du vill aligna och 
struct1 och struct2 är namnen på de två strukturerna i pymol
fit (struct1 and resi 1-3), (struct2 and resi 1-3)

Göra posters grafiskt
använd programmet scribus

Rensa epsfiler till renare filer
eps2eps filnamn.eps nyttfilnamn.eps

Program för att hålla reda på projekt, anteckningar, tips m.m.
