Hi Maria, Lets first state your question how I understand it: You have some data processing procedure that reads data from some files and generates some output. This you want to repeat several times. Here is a solution. Encapsulate the data processing in a function, e.g. fun[] that takes a list of file names as input, reads the files and processes this input: fun[files_List] Second, Eeach processing (i) uses a bunch of files : {filei1,filei2,..}. We assemble these lists into a "super" list: files={ {file11,file12,..}, {file21,file22,..}, .. } We now map the data processing function to the files: fun /@ files this will sequentially process each sublist of files hope this helps, Daniel Maria Cristina Dias Tavares wrote: > Hi, > > I need to run a batch in Mathematica, so that I read data from > several files and execute the calculations and generate the graphics. > Then I read another group of data and perform the same calculation and > that goes on until the data finish. > > I just manage to do this by putting all the calculation in a single > cell, inside a Do.
