Thanks Thesisfun and awsoci for the reply.
I know that author of a software (like SPSS) is not supposed to be an author on every paper that uses it. But the author of SPSS does not go and sit with the people using it to help them use it. The software is published and people just cite it. My code is not published and I helped this girl go through every step from analyzing the data to setting up the code.
And code is like an optimized protocol. If there is someone trying to optimize a protocol and then another person comes and uses the protocol. Will the person who optimized the protocol wont get his/her name on the paper?
Maybe I am over reacting on this and it is okay to not have a name on that paper. I just want to know what would be the right thing to do. Should I fight for it or am I acting stupid here?

Hi. I am a third year PhD student and I have been working in computational biology. I wrote a code to do some analysis and it took me almost one year to get everything working. Now there is a post doc in our lab who is using my code to do her stuff. I even helped her to set everything up (although this did not take long). She presented a poster and did not put my name on it. I felt bad as I thought it would be obvious to have my name there. And now I am worried that she would not include my name in her paper either. I talked to my supervisor about it but his response was even worse. He said did not know what was the rule for authorship. I know without my help this project had not been completed so soon so I feel cheated and not acknowledged. I am angry with my supervisor. Any suggestions?

Hi DrJeckyll

Thank you for your reply. I do not want to draw chemical reactions but yes lines and shapes will help me draw what I want. It is quite difficult for me to explain what I exactly want to draw. I downloaded Autocad and I think this will solve my problem. Thanks once again. :)

Hi. Can anyone suggest me how to make pretty pictures for papers. I have to depict some enzymatic reaction mechanisms. I tried to do it in paint and power point, but it still does not look professional. I know GIMP and photoshop are two softwares used by graphic designers. Is it possible to make a picture from scratch with these softwares? I really like the pictures in books, I would like to make something like that. Thanks in advance. :)

Yes, you are right, it is not the biggest problem in the world. Thank you HazyJane. I will try to meet people and interact with them online. I think I was just demotivated and having these thoughts as I am anxious about how my PhD is going to be. I feel better now. :)

Hi TreeofLife, thank you for replying. I am in Biological Science. I will check for the travel funds with the Conferences. But my concern is also that everyone is leaving the place. Out lab is almost empty now. I am the only PhD student here and 2 Post-docs, 2 technicians and 2 Profs (including my supervisor). This makes me nervous about being here. I have always had a good academic record. Also, for PhD I got call from almost everywhere I applied to. I want to continue my career in research after PhD. But I dont know if I will make it somewhere good.

Hi friends. This is the first time I am posting here. But I have been reading the posts and it seems one can actually get help here.
I am a second year PhD student. I have not attended any conference yet. I know it is important to attend these conferences and meet people and talk about your work but I am in a country in the middle of nowhere. Its an island and flying from here is very expensive. My supervisor does not have a lot of money neither. I dont know what should I do. I also feel stupid to have joined here in first place. But I like the kind of work I do and that was the reason I joined. Also from outside it looked like a big group with lots of money but since moved in the story changed. 5 people left the place in one year. I am very worried about my career. I do not want to be stuck here for my entire life. I want to get a job/Post-doc after this. What should I do? Was this the worst decision of my life?
