test{2,1}=['0.0505163,+,ESI,ms1,-,line,1.1-834.0,254,1.1 26,1.2 16,1.3 52,1.4 30,1.5 12']

Are the fields 2-6 always 1,3,3,1,4 characters?
Also,after line you always have a float followed with by a negative float with no space in between?

Con sidering that I created a temp.txt containing:
0,+,ESI,ms1,-,line,1.1-790.4,275,1.1 41,1.2 30,1.6 10,1.7 24,1.9 30,1.9 20,2.0 18,2.0 41
0.0505163,+,ESI,ms1,-,line,1.1-834.0,254,1.1 26,1.1 16,1.2 52,1.3 30,1.4 12,1.8 23,2.0 17,2.1 12,2.4 11
0.103382,+,ESI,ms1,-,line,1.1-895.4,252,1.1 12,1.4 21,1.5 40,1.6 29,1.7 10,1.7 28,2.0 19,2.1 11,2.1 16,2.1 21,2.2 22,2.2 14,2.4 10,2.7 13,2.8 10,3.5 21,3.6 12,3.6 11,3.7 23,3.7 18,4.2 20,4.7 14,4.9 12,4.9 11
Edit
% To import:
fid = fopen('temp.txt');
fmt = '%f,%1s,%3s,%3s,%1s,%4s,%f%f,%f,%s';
% Tweak 4095*n to augment the buffer
opt = {'Delimiter','','CollectOutput',1,'BufSize',4095*3};
out = textscan(fid,fmt,opt{:});
out{end} = cellfun(@(x) textscan(x,'%f %f','Delimiter',',','CollectOutput',1),out{1,end});
fclose(fid);
Now every bit of data is in the right format but it's not stored in the best way.

Didn't see your answer because I didn't refresh. I knew about buffer size but was working also on an alternative in case your each the limit. Let me know if it works consistenlty, otherwise you can setup a loop with low level import with fscanf.
Cheers
