![]() I know I have to use textscan to accomplish this but I am unsure of the formatspec options needed to achieve this, since whichever setting I use seem to give me some jumbled form of cell output. ![]() The file comes out of a relational database (Antelope) and consists of earthquake location, dates, times, phase information, etc. file fopen ('file.txt') d textscan (file,'s d d d ,'delimiter',',') If i run the code above it gives me a 1 x n array. ![]() These are coordinates to regions of interest for each category in an image. Learn more about text file, block, textscan, text, read, parse, debug, debugging session, regexp, blocks MATLAB I have a text file that is in a rather funky format. So what I wanted the textscan to output was a 4 row cell array, the first row would have 6 cells representing the coordinates of the 6 regions for that specific row(in this case leaf tips). I want to read a text file into a cell array so that i have each line of my file as a new row and each attribute in my file as a column on that row. This question assumes that all you have is numerical values, so a cell array is indeed redundant, and it can be converted into a matrix, which is much easier to manipulate. Here you have a cell array that stores both columns of numbers and strings. Each row is delimited by an end-of-line ( EOL) character sequence. Each field consists of a group of characters delimited by a field delimiter character. ![]() Each block consists of a number of internally consistent fields. If trailing delimiters should invoke the missing-contents behaviour (your interpretation) then that would imply that the 123 should be accepted by the first time %f is processed, then the abc should be accepted by the first time %q is processed, then the empty field at the end of the line should be accepted and turned into nan by the second time %f is processed, then the 456 should be accepted and turned into character vector by the second time %q is processed, then the def should trigger a format mismatch the third time %f is processed, stopping the scanning and leaving def, in the buffer.I have the following text file: Leaf Tips:2867.5,1101.66666666667 2555,764.166666666667 2382.5,1221.66666666667 2115,759.166666666667 1845,1131.66666666667 1270,991.666666666667 When the field width operator is used with single characters ( c ), textscan also reads delimiter, white-space, and end-of-line characters. 1 A cell array is an array that can store values of different types. The textscan function regards a text file as consisting of blocks. To read additional data from the file after N cycles, call textscan again using the original fileID. example C textscan (fileID,formatSpec,N) reads file data using the formatSpec N times, where N is a positive integer. For example if the input were 123,abc,456,def, and the format were %f%q then with the current behaviour that would generate. The textscan function reapplies formatSpec throughout the entire file and stops when it cannot match formatSpec to the data. Yes, textscan could have been designed to set an internal flag indicating that a delimiter had been seen before the current position, but I am not sure that would meet with expectations.
